AI Technical Summary
In existing thermal protector detection and sorting devices, thermal protectors are prone to deviating from the predetermined track due to the short distance between the collection boxes, resulting in qualified and unqualified products being mixed together, and the sorting accuracy is insufficient.
The material distribution air knife replaces the pneumatic push rod, using high-pressure air thrust to blow the thermal protector into the corresponding collection box. Combined with the tilting table and side plate design, it ensures that the thermal protector slides down the predetermined path, reducing frictional resistance and improving sorting accuracy.
This effectively prevents the thermal protector from deviating from the track, improves the accuracy of sorting, and facilitates identification and analysis of defective products by marking them, thereby enhancing production quality control.

Abstract
Description
Technical Field
[0001] This application relates to the field of thermal protector sorting technology, and in particular to a thermal protector detection and sorting device that provides accurate sorting. Background Technology
[0002] As a critical safety component in various electrical appliances, the performance of thermal protectors directly affects the safety and reliability of equipment operation. In products such as air conditioners, refrigerators, and motors, thermal protectors must quickly cut off the circuit when the equipment overheats abnormally, preventing serious accidents such as fires and equipment damage caused by excessive temperatures. With the continuous expansion of the electrical product market, the demand for thermal protectors is increasing, making quality control particularly important. A thermal protector detection and sorting device with accurate sorting capabilities has emerged to address this need.
[0003] Currently, common thermal protector testing and sorting devices typically include a testing unit and a sorting unit. After the thermal protectors are tested, they are sorted by the sorting unit. The sorting unit generally uses pneumatic pushers to push qualified products to the qualified product collection box and unqualified products to the unqualified product collection box. At the same time, the pneumatic pushers are used to sort the products by moving two adjacent collection boxes.
[0004] Regarding the aforementioned technologies, the inventors believe that when the pneumatic pusher pushes the thermal protector into the collection box, because the two collection boxes are close together, the thermal protector may deviate from the predetermined track and fall into the wrong collection box, resulting in a mixture of qualified and unqualified products. Utility Model Content
[0005] The purpose of this application is to provide an accurate thermal protector detection and sorting device to improve the problem that thermal protectors may deviate from the predetermined track and fall into the wrong collection box, resulting in a mixture of qualified and unqualified products.
[0006] This application provides a thermal protector detection and sorting device for accurate sorting, which adopts the following technical solution:
[0007] A thermal protector detection and sorting device with accurate sorting capabilities includes a frame, a feeding and heating mechanism mounted on the frame, and a detection component mounted on the frame and located at the outlet end of the feeding and heating mechanism. The detection component includes a fixed frame and a drive component inverted on the fixed frame. The output end of the drive component is provided with a detection plate, and the detection plate is provided with a detection head. A detection platform for placing thermal protectors to be tested is provided below the detection plate on the frame. Collection boxes are provided on both sides of the frame, and the two collection boxes are used to collect qualified thermal protectors and unqualified thermal protectors, respectively. A separating air knife is provided on both sides of the frame on the detection platform to blow the thermal protectors into the opposite collection box.
[0008] By adopting the above technical solution, and replacing the traditional pneumatic push rod sorting with a material-distributing air knife, the thermal protector is blown into the corresponding collection boxes on both sides of the frame by the thrust of high-pressure air. This avoids the problem of qualified and unqualified products being mixed due to the thermal protector deviating from the track under the push of the pneumatic push rod because the collection boxes are close together. This improves the accuracy of sorting.
[0009] Optionally, the testing platform is equipped with inclined platforms on both sides to allow the heating protector to slide off.
[0010] By adopting the above technical solution, when the high-pressure air ejected by the material distribution air knife pushes the thermal protector, the tilting platform provides a slope that allows it to slide down smoothly, reducing the frictional resistance between the thermal protector and the testing platform. Combined with the blowing action of the material distribution air knife, the thermal protector can slide down the testing platform more smoothly.
[0011] Optionally, side plates are provided on both sides of the tilting platform.
[0012] By adopting the above technical solution, when the thermal protector slides down the inclined platform, the side plate can prevent the thermal protector from sliding down from both sides of the inclined platform, so that it enters the collection box along the predetermined path, which helps to prevent the thermal protector from deviating from the direction during the sliding process.
[0013] Optionally, a baffle is provided on the top surface of the testing platform to block the thermal protector after it has been processed by the feeding and heating mechanism.
[0014] By adopting the above technical solution, the baffle on the top surface of the testing platform can block the thermal protector after it has been processed by the feeding and heating mechanism, keeping it in a fixed and suitable position on the testing platform. This facilitates the testing head to accurately detect the temperature and on / off status of the thermal protector, helping to ensure the accuracy and stability of the testing process.
[0015] Optionally, a second driving component is provided on the side of the fixing frame near the testing table, and the output end of the second driving component is provided with a marking head for marking unqualified thermal protectors.
[0016] By adopting the above technical solution and marking defective products, production personnel can quickly identify defective products, which facilitates the statistical analysis of production batches and causes of failure of defective products. This helps to improve production processes in a targeted manner and enhance the overall quality of products.
[0017] Optionally, the output end of the second drive unit is provided with a plug rod, and the marking head is provided with a slot.
[0018] By adopting the above technical solution, the plug at the output end of the second drive unit cooperates with the slot on the marking head to achieve a detachable connection of the marking head. In actual use, the marking head may wear out or be damaged due to long-term use. This detachable structure allows for convenient and quick replacement of the marking head, reducing the maintenance cost and difficulty of the equipment.
[0019] Optionally, the baffle is provided with a dotting hole for the output end of the second drive component to pass through, and when the second drive component retracts, the marking head is located in the dotting hole.
[0020] By adopting the above technical solution, it is ensured that the marking head is in a proper position when not in operation, avoiding collisions with the thermal protector or other components that could cause damage. At the same time, the dotted holes provide precise guidance for the extension and retraction of the marking head.
[0021] Optionally, the collection box is inclined with a guide plate on the side away from the frame.
[0022] By adopting the above technical solution, the guide plate helps to guide the thermal protector blown off by the distributing air knife to slide smoothly into the collection box.
[0023] In summary, this application includes at least one of the following beneficial technical effects of a thermal protector detection and sorting device that provides accurate sorting:
[0024] 1. By setting up a material distribution air knife to replace the traditional pneumatic push rod sorting, the thermal protector is blown into the corresponding collection box on both sides of the frame by the thrust of high-pressure air. This avoids the problem of qualified and unqualified products being mixed due to the thermal protector deviating from the track under the push of the pneumatic push rod because the collection boxes are close together. This improves the accuracy of sorting.
[0025] 2. When the high-pressure air ejected by the distribution air knife pushes the thermal protector, the inclined table provides a slope for it to slide down smoothly, which reduces the frictional resistance between the thermal protector and the test table. Combined with the blowing action of the distribution air knife, the thermal protector can slide down the test table more smoothly.
[0026] 3. By marking defective products, production personnel can quickly identify them, facilitating the statistical analysis of production batches and causes of failure for defective products. This helps to improve production processes in a targeted manner and enhance overall product quality. Attached Figure Description

Detailed Implementation
[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0032] A thermal protector detection and sorting device with accurate sorting capabilities, referring to Figure 1 It includes a frame 1, a feeding and heating mechanism 2 mounted on the frame 1, and a detection component 3 mounted on the frame 1 and located at the outlet end of the feeding and heating mechanism 2. The frame 1 serves as the supporting foundation for the entire device.
[0033] Reference Figure 1 The feeding and heating mechanism 2 includes a slide rail 21 located on the top surface of the frame 1 and arranged along the length of the frame 1. The slide rail 21 is inclined to guide the thermal protector to slide from high to low. In this embodiment, the inclination angle is preferably 30° so that the thermal protector slides down slowly and is fully heated. At the same time, the groove of the slide rail 21 is adapted to the thermal protector to ensure that the trajectory is relatively uniform.
[0034] Reference Figure 1 The chute frame 21 is bolted to the top surface of the frame 1. It is made of stainless steel with a smooth surface to reduce friction when the thermal protector slides. The feeding and heating mechanism 2 also includes a vibratory feeder 22, which is an automatic feeding device. Its internal vibration mechanism causes the thermal protector to vibrate along a specific track and be conveyed to the outlet. The outlet of the vibratory feeder 22 is connected to the higher end of the chute frame 21 via a transition plate. One end of the transition plate is welded to the outlet of the vibratory feeder 22, and the other end is bolted to the top surface of the chute frame 21.

The detection plate 4 is equipped with a detection head 41, a high-precision temperature and on / off detection sensor capable of accurately detecting parameters such as the operating temperature, reset temperature, and on / off performance of the thermal protector. The detection head 41 is threaded onto the detection plate 4. Below the detection plate 4, the frame 1 has a detection platform 5 for placing the thermal protector under test. The detection platform 5 is fixed to the frame 1 by bolts, and its flat surface is used to stably place the thermal protector.
[0037] Reference Figure 1 , Figure 2 Collection boxes 6 are provided on both sides of the frame 1. The two collection boxes 6 are used to collect qualified thermal protectors and unqualified thermal protectors respectively. The collection boxes 6 are made of welded metal plates and have a certain capacity. A guide plate 61 is inclinedly provided on the side of the collection box 6 away from the frame 1. The guide plate 61 is fixed to the side of the collection box 6 by welding. Its function is to guide the thermal protector to slide smoothly into the collection box 6.
[0038] Reference Figure 1 , Figure 2 The frame 1 is located on both sides of the testing table 5 and is equipped with a material distribution air knife 7 that can blow off the thermal protectors into the collection box 6. The material distribution air knife 7 is fixedly installed on the frame 1 by bracket bolts. Its air inlet is connected to an external high-pressure air source through an air pipe. After the test is completed, according to the test results of the thermal protectors, high-pressure air is sprayed out by activating different material distribution air knives 7 to blow the qualified thermal protectors into the qualified product collection box 6 and blow the unqualified thermal protectors into the unqualified product collection box 6.
[0039] Reference Figure 2 The top surface of the testing table 5 is provided with a baffle 52, which is made of metal sheet and is fixedly installed on the top surface of the testing table 5 by bolts. Its function is to block the thermal protector after it has been processed by the feeding heating mechanism 2, so that the thermal protector stays on the testing table 5 and waits for testing. The two sides of the testing table 5 are integrally provided with inclined platforms 51 for the thermal protector to slide down, and the two sides of the inclined platforms 51 are integrally provided with side plates 511.
[0040] Reference Figure 2 , Figure 3A second driving component 8 is installed on the side of the fixed frame 31 near the testing table 5. The second driving component 8 is a slow-speed telescopic cylinder, which is fixedly installed on the side of the fixed frame 31 by bolts. The output end of the second driving component 8 is provided with a marking head 82 for marking unqualified thermal protectors. The marking head 82 is a color block and uses color marking. The output end of the second driving component 8 is also provided with a plug rod 81, which is welded and fixed to the output end of the second driving component 8. The marking head 82 is provided with a slot 821, and the plug rod 81 is inserted into the slot 821 with an interference fit, realizing the detachable connection between the marking head 82 and the second driving component 8, which facilitates the replacement of the marking head 82.
[0041] Reference Figure 2 The baffle 52 is provided with a dotting hole 521 for the output end of the drive component 8 to pass through. When the drive component 8 retracts, the marking head 82 is located in the dotting hole 521. When a defective thermal protector is detected, the drive component 8 extends and drives the marking head 82 to mark the defective thermal protector.
[0042] The implementation principle of this application embodiment is as follows:
[0043] In actual operation, the thermal protector to be tested is first placed in the vibratory feeder 22. Vibration causes it to exit from the outlet along a specific track, slide through a transition plate into the inclined slide rail 21, and simulate a high-temperature environment under the action of the heating plate 211. The heated thermal protector then slides towards the testing assembly 3 under gravity. Upon reaching the testing table 5, it is blocked by the baffle 52. A telescopic cylinder drives the testing plate 4 and the testing head 41 to detect the temperature change and on / off status of the thermal protector. The detection signal is transmitted to the control system to determine whether it is qualified. If it is unqualified, another telescopic cylinder drives the marking head 82 to mark it. Finally, the sorting air knife 7, according to the control system's instructions, blows the qualified and unqualified thermal protectors into the corresponding collection boxes 6. This helps reduce the mixing of qualified and unqualified products, and the marking facilitates differentiation, contributing to efficient and accurate testing and sorting.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
