Description

Technical Field

[0001] This application relates to the field of precast concrete technology, and in particular to a release agent application device for the production of cement concrete precast components. Background Technology

[0002] Mold release agent is a functional substance that lies between the mold and the finished product. It is chemically resistant and does not dissolve when in contact with the chemical components of different resins, especially styrene and amines. It also possesses heat and stress resistance, is not easily decomposed or worn, and adheres to the mold without transferring to the processed part, without hindering painting or other secondary processing operations.

[0003] Concrete blocks are a commonly used material in building construction. Concrete blocks include cubic concrete blocks and cylindrical concrete blocks, etc. They are often formed by casting and demolding concrete test molds. In order to facilitate the removal of cured concrete components, a release agent needs to be evenly applied to the surface of the precast concrete mold before casting. The release agent can produce a release film that acts as a lubricant and barrier, effectively reducing the adhesion between the concrete and the formwork, and allowing the concrete to detach smoothly from the formwork during demolding, thus maintaining the integrity and smoothness of the concrete shape.

[0004] The existing mold release agent coating device includes a frame, a storage bottle mounted on top of the frame, a feeding mechanism connected to the lower outlet of the storage bottle, a hand-operated control mechanism mounted on the frame below the storage bottle, and a mounting base fixed to the lower part of the frame. Two coating brackets are hinged to the left and right sides of the mounting base via damping shafts, and a coating roller is rotatably mounted on the lower end of each coating bracket. This structure continuously supplies mold release agent to the coating rollers through the storage bottle, ensuring a constant supply of appropriate mold release agent on the coating rollers and improving coating efficiency.

[0005] This device requires an operator to push it via a manual control mechanism. The coating roller contacts the template, evenly applying the release agent. The flow rate of the release agent can be adjusted via a flow regulating valve to maintain optimal humidity on the coating roller. After moving from one end of the template to the other, the device is then moved laterally a short distance, approximately the axial distance between the two coating rollers. This allows one of the coating rollers to move to the uncoated area left between the two rollers during the first coat. This process is repeated until the coating is complete. Furthermore, this spraying method is labor-intensive, time-consuming, and inefficient. The quality and effect of the coating also vary from person to person, potentially resulting in uneven application and inconsistent quality. Summary of the Invention

[0006] To address the aforementioned problems, this application provides a release agent application device for the production of precast cement concrete components.

[0007] The release agent application device for the production of precast cement concrete components provided in this application adopts the following technical solution:

[0008] A release agent application device for the production of precast cement concrete components includes:

[0009] An annular base, wherein the annular base is provided with a cleaning through hole and a coating through hole;

[0010] A turntable is located inside the annular base. A first robotic arm is provided on the turntable. The rotation of the turntable drives the first robotic arm to rotate, so that the first robotic arm has a clamping station, a cleaning station, a coating station and a return station located around the turntable. The cleaning station is located above the cleaning through hole, and the coating station is located above the coating through hole.

[0011] A cleaning mechanism, located below the cleaning through hole, is used to scrape away debris from the inner wall of the mold when the first robotic arm clamps the mold to the cleaning station.

[0012] A coating mechanism is located below the coating through hole and is used to coat the inner wall of the mold when the first robot arm clamps the mold to the coating station.

[0013] By adopting the above technical solution, this mold release agent application device integrates a ring base, a turntable, a cleaning mechanism, and a coating mechanism, realizing automated cleaning of the mold's inner wall and application of the mold release agent. The ring base is equipped with cleaning and coating through-holes, corresponding to the cleaning and coating stations respectively, ensuring precise positioning of the mold at different stations. The robotic arm on the turntable moves between stations as the turntable rotates, realizing continuous automated operation of mold clamping, cleaning, coating, and return. This improves production efficiency and the uniformity of mold release agent application, reduces labor intensity, and ensures consistent coating quality through automated control, contributing to improved preform production efficiency and finished product quality.

[0014] Optionally, the coating mechanism includes a second robotic arm located next to the annular base, a movable body, and a brush strip; the movable body includes a drive motor fixed to the second robotic arm and a movable head mounted on the drive motor, the movable head being provided with a brush strip.

[0015] By adopting the above technical solution, the setting of the second robotic arm makes the movement of the main body and the brush head more flexible, achieving efficient coating of the inner wall of the mold.

[0016] Optionally, the movable head is detachably mounted to the drive motor; the movable head includes multiple movable plates, each of which is Reuleaux triangle in shape and of the same size, and each of which is provided with the brush strip around its periphery, with the brush strip provided on the end face of the movable plate furthest from the drive motor;

[0017] When multiple movable pieces are aligned and stacked, the movable head is movably mounted on the output shaft of the drive motor, so that the rotation of the output shaft of the drive motor causes the edge of the movable piece to move in a square trajectory;

[0018] When multiple movable pieces are stacked in an alternating manner, the movable head is fixedly mounted on the output shaft of the drive motor, so that the rotation of the output shaft of the drive motor causes the edge of the movable piece to move in a circular trajectory.

[0019] While conventional coating rollers are convenient for coating flat surfaces, they create blind spots when coating circular surfaces and are not ideal for applying release agent to the sidewalls of cylindrical molds. By employing the aforementioned technical solution, the drive motor in the moving body works in conjunction with the moving head, allowing the moving head to adapt to the specific shape of the mold (square or circular), thus ensuring that the release agent is applied evenly and precisely to the inner wall of the mold. This not only improves the flexibility and adaptability of the coating device but also increases the efficiency of release agent application, ensures consistent coating quality, reduces the uncertainty and labor intensity of manual operation, and minimizes material waste.

[0020] Optionally, the structure of the cleaning mechanism is consistent with the structure of the active body, and the outer triangle formed by the active plate of the brushing mechanism and the brush strip is consistent in shape and size with the outer triangle of the active plate of the cleaning mechanism.

[0021] By adopting the above technical solution, due to the similarity between the cleaning mechanism and the main structure of the device, the process from cleaning to coating can be completed without complex structural changes. This not only improves the production efficiency of the coating device but also reduces the maintenance cost of the coating device.

[0022] Optionally, the annular base is provided with an arc-shaped perforation, the extension direction of which is consistent with the trajectory of the first robotic arm, one end extending to the coating station and the other end extending to the return station; the first robotic arm is used to rotate the mold to face downwards until the mold moves to the return station after the coating mechanism coats the inner wall of the mold, and the first robotic arm is used to rotate the mold to face upwards.

[0023] Using ordinary coating rollers can easily lead to uneven application, often resulting in excess release agent at the bottom of the mold. This not only wastes the release agent but also makes it difficult to mark the concrete specimen surface due to excessive release agent, affecting the strength of the concrete specimen. By adopting the above technical solution, the first robotic arm can smoothly rotate the mold with the opening facing downwards after coating, facilitating the drainage of excess release agent, reducing material waste, and ensuring mold cleanliness, thus preparing for subsequent processes. Furthermore, the first robotic arm rotates the mold with the opening facing upwards when it reaches the return position; this continuous action improves the smoothness and automation of the operation, reduces manual intervention, and enhances production efficiency and operational safety.

[0024] Optionally, when the first robotic arm moves to the coating station, the first robotic arm extends into the coating through hole so that the mold is located below the annular base, and the mold opening faces to the side, and the coating mechanism extends into the mold along a horizontal movement trajectory.

[0025] By adopting the above technical solution, the coating mechanism extends into the mold along a horizontal movement trajectory and effectively coats the inner wall of the mold from the side. This not only improves the accuracy and uniformity of the coating, but also prevents the release agent from flowing down onto the coating mechanism, thereby preventing contamination of the coating mechanism and ensuring a clean and efficient coating process.

[0026] Optionally, when multiple movable pieces are aligned and stacked, after the coating mechanism coats the inner wall of the mold, the first robotic arm is used to drive the mold to rotate.

[0027] When multiple movable pieces are stacked in an alternating manner, the first robotic arm is used to drive the mold to rotate when the coating mechanism coats the inner wall of the mold.

[0028] By adopting the above technical solution, when the movable pieces are aligned and stacked, during the application of the coating to the inner wall of a square mold, the first robotic arm rotates the mold after application, resulting in a more uniform application of the release agent to the inner wall of the mold. Conversely, when the movable pieces are staggered and stacked, during the application of the coating to the inner wall of a circular mold, the first robotic arm rotates the mold during the application process, again resulting in a more uniform application of the release agent to the inner wall of the mold. The first robotic arm adapts to the mold rotation requirements under different coating mechanism configurations, ensuring consistent coating quality.

[0029] Optionally, an air blowing mechanism is also included, which is located on one side of the cleaning mechanism and is used to blow air into the mold after the cleaning mechanism has scraped the inner wall of the mold.

[0030] By adopting the above technical solution, after the cleaning mechanism scrapes away the debris from the inner wall of the mold, the air blowing mechanism blows air to clean the inside of the mold, effectively removing residual debris and impurities, improving the adhesion of the release agent and the demolding efficiency of the mold.

[0031] Optionally, a first conveyor belt located next to the clamping station is also included for receiving the mold and conveying it to the annular base.

[0032] By adopting the above technical solution, the mold can be directly received by the first robotic arm from the first conveyor belt and then smoothly transported to the annular base for subsequent cleaning and coating processes. This automated conveying method not only reduces the need for manual operation and lowers labor intensity, but also improves the continuity and stability of production.

[0033] Optionally, a second conveyor belt located next to the return station is also included for receiving the mold and conveying it away from the turntable.

[0034] By adopting the above technical solution, after the coating process is completed, the mold can be placed onto the second conveyor belt by the first robotic arm and transported away from the turntable, preparing the mold for subsequent processing or storage. This process not only reduces manual intervention and the risk of operational errors and mold damage, but also ensures the continuity and stability of the production process.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. This mold release agent application device integrates a ring base, turntable, cleaning mechanism, and application mechanism, realizing automated cleaning of the mold inner wall and application of mold release agent. The robotic arm on the turntable moves between various workstations as the turntable rotates, achieving continuous automated operation of mold clamping, cleaning, application, and return. This improves production efficiency and the uniformity of mold release agent application, reduces labor intensity, and ensures consistent application quality through automated control, thus contributing to improved preform production efficiency and finished product quality.

[0037] 2. The drive motor in the main body works in conjunction with the moving head, allowing the moving head to be adaptively adjusted according to the specific shape of the mold (square or round), thereby ensuring that the release agent can be evenly and accurately coated on the inner wall of the cube mold and the cylindrical mold.

[0044] The following will be combined with the appendix Figure 1-4 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] This application discloses a release agent application device for the production of precast cement concrete components. The release agent application device (hereinafter referred to as the application device) is used to coat the inner wall of a concrete test block mold with a release agent. The concrete test blocks include cubic and cylindrical test blocks, and the corresponding mold cross-sections are square and circular, respectively.

[0046] Reference Figure 1 The coating device includes an annular base 1, a turntable 2, a first robotic arm 3, a cleaning mechanism 4, a coating mechanism 5, an air blowing mechanism, a first conveyor belt 6, and a second conveyor belt 7.

[0047] The turntable 2 is located inside the annular base 1. The turntable 2 includes a turntable body and a drive mechanism. The drive mechanism is located below the turntable body, connected to the turntable body, and drives the turntable body to rotate. A first robotic arm 3 is provided on the turntable body. The rotation of the turntable body drives the first robotic arm 3 to rotate, so that the first robotic arm 3 is always located above the annular base 1. The first robotic arm 3 has a clamping station 31, a cleaning station 32, a painting station 33, and a return station 34 located around the turntable 2.

[0048] The first conveyor belt 6 is located next to the clamping station 31 and is used to receive molds and transport them to the annular base 1. When the first robot arm 3 is located at the clamping station 31, it clamps the mold on the first conveyor belt 6. The second conveyor belt 7 is located next to the return station 34 and is used to receive molds and transport them away from the turntable 2. When the first robot arm 3 is located at the return station 34, it returns the clamped mold to the second conveyor belt 7 for the next process.

[0049] The annular base 1 is provided with a cleaning through hole 11 and a coating through hole 12. The cleaning station 32 is located above the cleaning through hole 11, and the coating station 33 is located above the coating through hole 12.

[0050] The cleaning mechanism 4 is located below the cleaning through hole 11 and is used to scrape away debris from the inner wall of the mold when the first robot arm 3 clamps the mold to the cleaning station 32. The air blowing mechanism (not shown in the figure) is located on one side of the cleaning mechanism 4 and is used to blow air to clean the inside of the mold after the cleaning mechanism 4 has scraped the inner wall of the mold.

[0051] The coating mechanism 5 is located below the coating through hole 12 and is used to coat the inner wall of the mold when the first robot arm 3 clamps the mold to the coating station 33.

[0052] Specifically, the mold is placed on the first conveyor belt 6 for transmission. The turntable 2 rotates, causing the first robotic arm 3 to rotate to the clamping station 31. The first robotic arm 3 is located next to the first transmission belt. After clamping the mold, the turntable 2 rotates, causing the first robotic arm 3 to rotate to the cleaning station 32. The cleaning mechanism 4 scrapes away debris from the inner wall of the mold, and then the air blowing mechanism blows air into the mold to clean it. The turntable 2 continues to rotate, causing the first robotic arm 3 to rotate to the coating station 33. The coating mechanism 5 applies a release agent to the inner wall of the mold. The turntable 2 continues to rotate, causing the first robotic arm 3 to rotate to the return station 34, placing the mold on the second conveyor belt 7 for the next process.

[0053] During the cleaning process, the mold opening faces downwards. During the coating process, the mold is located below the annular base 1, and the opening faces to the side.

[0054] The painting mechanism 5 includes a second robotic arm 51 located next to the annular base 1, a movable body 52, and a brush strip 53. The movable body 52 includes a drive motor 521 fixed to the second robotic arm 51 and a movable head 522 mounted on the drive motor 521. The movable head 522 is provided with a brush strip 53.

[0055] In this embodiment, the movable head 522 is detachably mounted to the drive motor 521. The movable head 522 includes multiple movable plates, each of which is Reuleaux triangle in shape and of the same size, and each has a brush strip 53 on its periphery. The end face of the movable plate furthest from the drive motor 521 is provided with the brush strip 53.

[0056] When multiple movable pieces are aligned and stacked, the movable head 522 is movably mounted on the output shaft of the drive motor 521, so that the rotation of the output shaft of the drive motor 521 causes the edge of the movable piece to move in a square trajectory.

[0057] When multiple movable pieces are stacked in an alternating manner, the movable head 522 is fixedly mounted on the output shaft of the drive motor 521 so that the rotation of the output shaft of the drive motor 521 causes the edge of the movable piece to move in a circular path.

[0058] Reference Figure 2 When multiple movable pieces are aligned and stacked, a rotating part 523 is rotatably connected to the middle of the output shaft of the drive motor 521, and a first bevel gear 524 is fixedly connected to its end. A connecting rod 525 is fixedly connected to the movable head 522, and a second bevel gear 526 is fixedly connected to the middle of the connecting rod 525. The end of the connecting rod 525 is located to the side of the first bevel gear 524 and is fixedly connected to the rotating part 523. The first bevel gear 524 and the second bevel gear 526 mesh. The output shaft of the drive motor 521 rotates, driving the first bevel gear 524 to rotate, thereby driving the second bevel gear 526 to rotate around the first bevel gear 524, so that the outermost movement trajectory of the movable head 522 is square, which can coat the inner wall of the square mold.

[0059] Reference Figure 3 When multiple movable pieces are stacked in a staggered manner, the connecting rod 525 is fixedly connected to the output shaft of the drive motor 521. The output shaft of the drive motor 521 rotates, causing the connecting rod 525 to rotate, which in turn causes the movable head 522 to rotate, making the outermost circle of the movable head 522 move in a circular motion, which can coat the inner wall of the circular mold.

[0060] The structure of the cleaning mechanism 4 is the same as that of the active body 52. ​​The outer triangle formed by the active plate of the brushing mechanism 5 and the brush strip 53 is the same in shape and size as the outer triangle of the active plate of the cleaning mechanism 4.

[0061] The annular base 1 is provided with an arc-shaped perforation 13. The extension direction of the arc-shaped perforation 13 is consistent with the trajectory of the first robot arm 3. One end extends to the coating station 33 and the other end extends to the return station 34. The first robot arm 3 is used to rotate the mold to the opening facing down until the mold moves to the return station 34 after the coating mechanism 5 coats the inner wall of the mold. The first robot arm 3 is used to rotate the mold to the opening facing up.

[0062] After applying the release agent to the inner wall of the mold, the first robotic arm 3 rotates the mold so that the opening faces downwards, allowing excess release agent to flow out. A collection groove can be provided below the annular base 1, with the extension direction of the collection groove being consistent with the extension direction of the arc-shaped perforation 13, to collect the release agent flowing down into the mold.

[0063] When the first robotic arm 3 moves to the coating station 33, it extends into the coating through hole 12, positioning the mold below the annular base 1 with the mold opening facing to the side. The coating mechanism 5 extends into the mold along a horizontal movement trajectory. Coating the inner wall of the mold from the side prevents the release agent from flowing downwards onto the coating mechanism 5 and contaminating it.

[0064] When multiple movable pieces are aligned and stacked, the coating mechanism 5 coats the inner wall of the mold, and then the first robotic arm 3 drives the mold to rotate; when multiple movable pieces are staggered and stacked, the coating mechanism 5 coats the inner wall of the mold, and then the first robotic arm 3 drives the mold to rotate, so that the release agent in the mold is more even.
