Description

Technical Field

[0001] This utility model relates to the field of kitchenware production equipment technology, specifically a device for detecting the anti-coating peeling of cookware. Background Technology

[0002] Devices for testing the resistance of cookware coatings to peeling typically assess the adhesion of the coating by simulating wear and scratches during actual use of the cookware, observing whether the coating peels off and the degree of peeling, thereby determining the cookware's resistance to coating peeling.

[0003] Chinese patent discloses a scratch testing device for the surface coating of a frying pan (publication number CN218271636U). The patent includes a workbench, on the upper surface of which is mounted a rotatable turntable. Several mounting grooves are evenly distributed around the center of the turntable above the turntable. A cookware placement mechanism is detachably mounted at the mounting groove. The cookware placement mechanism includes a sleeve, which is placed inside the mounting groove. A cookware storage tray is slidably connected inside the sleeve. The upper part of the cookware storage tray has a bowl-shaped structure and an internal cookware storage cavity. The lower part of the cookware storage tray has a straight cylindrical structure and is slidably connected to the sleeve.

[0004] Therefore, based on the above search and combined with existing technology, since the cookware itself has a curved side, this patent can only polish the bottom surface of the inner cavity of the cookware. However, in actual use, the side walls and other parts of the cookware will also be subject to friction and scratches. Polishing only the bottom surface cannot simulate the overall usage conditions, cannot fully test the anti-coating peeling performance of the cookware, and the evaluation results are biased, resulting in insufficient quality control. It is impossible to test the coating adhesion of key parts such as the side walls, which affects the product quality. Utility Model Content

[0005] The purpose of this invention is to provide a device for detecting the peeling of the coating on cookware, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for detecting anti-coating peeling of cookware includes a base frame, a conveyor belt fixedly mounted on the top surface of the base frame, a fixed platform fixedly mounted on one side of the base frame, and a robotic arm fixedly mounted on the top surface of the fixed platform.

[0008] The output end of the robotic arm is rotatably mounted with a rotating tube, and the bottom end of the rotating tube is fixedly connected to a grinding head for polishing the coating. The top of the grinding head is equipped with an auxiliary structure for multi-faceted inspection of the cookware.

[0009] The inner cavity of the base frame is fixedly equipped with a control box for controlling the overall operation of the device, and the outer wall of the conveyor belt is fixedly equipped with multiple positioning structures for limiting and fixing the pot.

[0010] As a further embodiment of this utility model, the auxiliary structure includes a diversion pipe, and a plurality of fixed pipes are fixedly connected to the outer wall of the diversion pipe. Each fixed pipe is equipped with a grinding plate for friction detection of the side of the cookware on the side away from the diversion pipe. A sliding rod is fixedly connected to the inner wall of each grinding plate, and one end of the sliding rod is slidably located in the inner cavity of the fixed pipe.

[0011] As a further embodiment of this utility model, the outer wall of the rotating tube is rotatably connected to multiple sets of auxiliary rods for ensuring the smooth expansion of the grinding plate, and the inner wall of each grinding plate is rotatably connected to a transmission rod, and the transmission rod is rotatably connected to the auxiliary rod.

[0012] As a further embodiment of this utility model, the output end of the robotic arm is fixedly connected to a fixed frame, and a motor for providing rotational power to the rotating tube is fixedly installed in the inner cavity of the fixed frame, and the motor and the rotating tube are rotatably connected by a belt.

[0013] As a further embodiment of this utility model, the positioning structure includes a fixed plate, and multiple fixed plates are provided and symmetrically and evenly distributed on the outer surface of the conveyor belt. A support ring for initially supporting the pot is fixedly installed on the top of the fixed plate, and an electromagnetic plate for fixing the pot is fixedly installed on the upper surface of the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. When this utility model is used, an efficient and intelligent detection system is formed through an airflow-driven auxiliary structure. After the device is started, the airflow generated by the air pump is stably transported through the pipeline and evenly distributed to each pipeline through diversion. The airflow thrust drives the grinding plate to expand outward. Its arc design combined with a stable support structure can achieve adaptive fitting according to the different curvatures of the cookware's side surface. It can comprehensively simulate the friction and scratching of the cookware's side wall during actual cooking and cleaning, breaking through the limitations of traditional single bottom surface detection, effectively avoiding evaluation deviations caused by one-sided detection, making the anti-coating peeling performance test closer to the real use scenario, greatly improving the accuracy of the evaluation results, and providing a reliable basis for product quality judgment.

[0016] 2. When this utility model is used, the positioning structure, support ring and electromagnetic plate are used to make the cookware stable and fixed. Combined with the rotatable grinding head and multi-directional detection function, the adhesion of the coating on key parts such as the side wall is effectively detected, filling the gaps in quality control, ensuring product quality, and helping enterprises improve their market competitiveness.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 3 A device for detecting anti-coating peeling of cookware includes a base frame 1, a conveyor belt 2 fixedly installed on the top surface of the base frame 1, a fixed platform 3 fixedly installed on one side of the base frame 1, and a robotic arm 4 fixedly installed on the top surface of the fixed platform 3.

[0026] The output end of the robotic arm 4 is rotatably equipped with a rotating tube 5. The bottom end of the rotating tube 5 is fixedly connected to a grinding head 6 for polishing the coating. The top of the grinding head 6 is equipped with an auxiliary structure for multi-face testing of the cookware. Because the curved sides of the cookware are easily subjected to friction and scratches during use, the auxiliary structure can fit the curved sides to simulate the stress conditions in real use scenarios, enabling multi-face testing of the cookware. This allows for a more comprehensive and accurate assessment of the coating adhesion of various parts of the cookware, avoiding assessment deviations caused by only testing the bottom surface, reducing blind spots in product quality control, improving the reliability and effectiveness of test results, and providing a more accurate basis for judging the anti-coating peeling performance of the cookware.

[0027] The inner cavity of the base frame 1 is fixedly installed with a control box 7 for controlling the overall operation of the device, and the outer wall of the conveyor belt 2 is fixedly installed with multiple positioning structures for limiting and fixing the pot.

[0028] Specifically, the bottom surface of the base frame 1 is fixedly equipped with an adjustment base for easy adjustment of the device height. The conveyor belt 2 consists of a conveying active roller, a conveying driven roller, and a drive motor. The conveying active roller and the conveying driven roller are located at both ends of the inner cavity of the conveyor belt 2. One end of the conveying active roller is equipped with a drive motor to provide rotational power. The operation of the robotic arm 4 and the conveyor belt 2 is driven by the control box 7.

[0029] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 The auxiliary structure includes a diversion pipe 601, and multiple fixed pipes 602 are fixedly connected to the outer wall of the diversion pipe 601. Each fixed pipe 602 is equipped with a grinding plate 603 for friction detection of the side of the cookware on the side away from the diversion pipe 601. Each grinding plate 603 is fixedly connected to a sliding rod 604 on the inner wall, and one end of the sliding rod 604 is slidably located in the inner cavity of the fixed pipe 602.

[0030] Specifically, the diversion tube 601 is fixedly sleeved on the outer wall of the rotating tube 5, and the inner cavities of the two are connected to form an efficient airflow transmission channel. When the airflow enters the diversion tube 601 through the rotating tube 5, it will be evenly distributed to each fixed tube 602. At this time, the thrust generated by the airflow drives the sliding rod 604, which drives the grinding plate 603 to expand outward, so that the grinding plate 603 can accurately fit the arc-shaped inner wall of the cookware and realize all-round friction detection.

[0031] Specifically, to ensure the stability and sealing of airflow transmission, pistons 605 are installed in the inner cavity of the fixed tube 602, and they are tightly slidably connected to the inner wall of the fixed tube 602 to effectively prevent air leakage. One side of the piston 605 is fixedly connected to the sliding rod 604 to form a linkage structure. The grinding plate 603 is set as an arc plate, and multiple friction blocks are fixedly installed on it and the outer wall of the grinding head 6, which can better simulate the wear conditions in real use scenarios and provide a reliable basis for testing the anti-coating peeling performance of cookware.

[0032] The outer wall of the rotating tube 5 is rotatably connected by a connector to a number of auxiliary rods 606 for ensuring the smooth expansion of the grinding plate 603. The inner wall of each grinding plate 603 is rotatably connected by a transmission rod 607 through a connector. The transmission rod 607 and the auxiliary rod 606 are rotatably connected by a pin. Each set of auxiliary rods 606 and transmission rods 607 is provided with two rods, which are symmetrically and evenly distributed on the upper and lower sides of the fixed tube 602.

[0033] An air pump 608 is fixedly installed on one side of the base frame 1. As the power core of the entire airflow transmission system, the output end of the robotic arm 4 is fixedly connected to an air inlet pipe 609. The air pump 608 is fixedly connected to the air inlet pipe 609 through a pipe. The air inlet pipe 609 and the rotating pipe 5 are rotatably connected by a bearing, and their inner cavities are connected to each other, thus constructing a stable airflow input path. While ensuring smooth internal airflow, the presence of the bearing completely avoids the risk of the pipe getting tangled on the outer wall of the air inlet pipe 609 when the rotating pipe 5 rotates. This ensures that the airflow transmission system is stable, reliable, and does not interfere with each other during continuous operation, thereby improving the practicality and durability of the device.

[0034] Please see Figure 3 The output end of the robotic arm 4 is fixedly connected to a fixed frame 501. The inner cavity of the fixed frame 501 is fixedly installed with a motor 502 for providing rotational power to the rotating tube 5, and the motor 502 and the rotating tube 5 are rotatably connected by a belt 503.

[0035] Specifically, tensioning pulleys are fixedly fitted on the output shaft of motor 502 and the outer wall of rotating tube 5, and belt 503 is wound around the outer wall of the two sets of tensioning pulleys.

[0036] Example 2: Please refer to Figure 1 , Figure 6 Based on Embodiment 1, the positioning structure includes a fixed plate 201. Multiple fixed plates 201 are provided and are symmetrically and evenly distributed on the outer surface of the conveyor belt 2. A support ring 202 for initially supporting the pot is fixedly installed on the top of the fixed plate 201, and an electromagnetic plate 203 for fixing the pot is fixedly installed on the upper surface of the fixed plate 201.

[0037] Specifically, the support ring 202 is made of silicone with good toughness and has an inverted conical design. When the cookware is placed on it, the inverted conical structure can initially fix and limit the cookware, while leaving a suitable gap between the cookware and the electromagnetic plate 203. When the cookware moves to the bottom of the grinding head 6, the robotic arm 4 drives the grinding head 6 to press down, and the support ring 202 is squeezed and bent outward, causing the bottom of the cookware to fit tightly against the electromagnetic plate 203. At this time, the gravity sensor built into the electromagnetic plate 203 monitors the pressure change in real time. Once a contact signal is detected, the magnetic attraction function is immediately activated to firmly attract the cookware. After the test is completed, the robotic arm 4 returns to its original position and moves upward, removing the downward pressure. The electromagnetic plate 203 then demagnetizes, and the support ring 202 quickly rebounds to an upright position due to the elasticity of the silicone material, separating the cookware from the electromagnetic plate 203 again, making it convenient for the operator to quickly remove the cookware. The whole process is smooth and efficient, ensuring the convenience and stability of the test operation.

[0038] The working principle of this utility model is as follows:

[0039] First, the cookware is placed on the fixed plate 201 of the conveyor belt 2, and is initially limited by the inverted conical silicone support ring 202, so that a gap is formed between the cookware and the electromagnetic plate 203. When the cookware moves with the conveyor belt 2 to the bottom of the grinding head 6, the robotic arm 4 drives the grinding head 6 to press down, squeezing the support ring 202 to bend it, so that the cookware and the electromagnetic plate 203 are in contact. The gravity sensor in the electromagnetic plate 203 triggers the magnetic attraction function, and the cookware is firmly fixed.

[0040] Then, during the testing phase, the conveyor belt 2 stops operating, and the air pump 608 provides power. The airflow enters the rotating tube 5 through the pipe and the air inlet pipe 609, and then is evenly distributed to the fixed tube 602 through the diversion pipe 601. Under the thrust of the airflow, the sliding rod 604 drives the grinding plate 603 to expand outward and fit against the arc-shaped inner wall of the cookware. At the same time, the structure composed of the auxiliary rod 606 and the transmission rod 607 ensures that the grinding plate 603 expands smoothly. The rotating tube 5 rotates under the drive of the motor 502 and the belt 503. The friction blocks on the outer wall of the grinding plate 603 and the grinding head 6 are used to simulate actual wear, so as to realize the friction detection of the multi-sided coating of the cookware.

[0041] After the final inspection is completed, the robotic arm 4 resets, the electromagnetic plate 203 demagnetizes, and the support ring 202 rebounds to separate the cookware from the electromagnetic plate 203, making it easier for manual removal of unqualified cookware. At the same time, the conveyor belt 2 resumes operation and continues to transport qualified cookware.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
