Description

Technical Field

[0001] This utility model relates to the field of thermistor sorting technology, and in particular to an automatic rejection linkage device for defective products in a thermistor sorting machine. Background Technology

[0002] In the field of electronic component manufacturing, thermistors are widely used in home appliances, automotive electronics, and industrial control due to their temperature sensitivity. As downstream industries demand higher performance stability from thermistors, the production process requires precise screening of thermistors using sorting equipment to remove defective products, ensuring product quality and meeting the quality control needs of mass production. Therefore, efficient thermistor sorting devices have become key equipment in the industry's production chain.

[0003] While current thermistor sorting machines on the market can achieve basic sorting functions, they have significant shortcomings in practical applications. On the one hand, the good product storage structure of existing sorting machines is mostly fixed. Good products fall directly into the storage box after being conveyed, which easily leads to uneven accumulation due to the fixed falling position, requiring frequent manual cleaning. This not only increases labor costs but may also damage good products due to accumulation and compression. On the other hand, after defective products are rejected, the temporary storage structure often requires manual cleaning one by one. During the cleaning process, the equipment must be stopped or the products must be manually moved. This operation is cumbersome and inefficient, making it difficult to adapt to the continuous and efficient operation requirements of mass production. In response to this technical problem, this application proposes an automatic defective product rejection linkage device for thermistor sorting machines. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic rejection linkage device for defective products in a thermistor sorting machine. The device uses a sprocket and chain to drive a reciprocating threaded rod to rotate, causing the moving plate and storage box to move back and forth, thus preventing the accumulation of good products. When the operator steps on the foot pedal, the storage box is tilted via a traction rope, and the defective products fall into the moving box, achieving rapid unloading and transfer.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic defective product rejection linkage device for a thermistor sorting machine includes a sorting machine body, a conveyor mounted on the top side of the sorting machine body, a rejection component mounted on the rear side of the sorting machine body, a storage box mounted on the top side of the sorting machine body, a baffle rotatably connected to the rear side of the storage box, adjacent storage boxes connected by a connecting rod, a guide tube fixedly connected to the front side of the sorting machine body, the inner wall of the guide tube connected to one end of the connecting rod via a traction component, a moving platform fixedly connected to one side of the sorting machine body, a moving plate connected to the inner wall of the moving platform via a moving component, a rotating shaft rotatably connected to the rear side of the sorting machine body, and a rotating shaft mounted on the rear side of the conveyor, the rotating shaft being connected to the rotating shaft via a linkage component.

[0006] Furthermore, the traction assembly includes a guide wheel disposed on the top side of the sorting machine body, a traction rope disposed at one end of the connecting rod, a foot pedal fixedly connected to the bottom end of the traction rope, the traction rope being disposed inside the guide tube, and the traction rope being disposed on the outer wall of the guide wheel.

[0007] Furthermore, the moving component includes a slide rod fixedly connected to the inner wall of the moving platform, a moving plate disposed on the outer wall of the slide rod, a reciprocating threaded rod rotatably connected to the inner wall of the moving platform, the moving plate disposed on the outer wall of the reciprocating threaded rod, and the rear end of the reciprocating threaded rod being connected to a rotating shaft via a transmission component.

[0008] Furthermore, the transmission assembly includes a second sprocket fixedly connected to the reciprocating threaded rod and the rear end of the rotating shaft, and the linkage assembly includes a first sprocket fixedly connected to the middle end of the rotating shaft and the rear end of the rotating shaft.

[0009] Furthermore, the two sprockets and the two sprockets are connected by chains.

[0010] Furthermore, the rejection assembly includes an electric push rod disposed on the rear side of the sorting machine body, and a push plate is fixedly connected to the drive end of the electric push rod.

[0012] Furthermore, a guide bucket is provided at one end of the conveyor, and the guide bucket is located on the top side of the storage box.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the reciprocating threaded rod inside the moving platform is driven to rotate by sprocket one, sprocket two and chain transmission. Since the moving plate is fitted with a sliding rod and is threadedly connected to the reciprocating threaded rod, it will move back and forth along the sliding rod as the threaded rod rotates, thereby driving the storage box to move synchronously, so that the good products can be evenly distributed when they fall into the storage box through the guide hopper, effectively avoiding uneven accumulation of good products.

[0014] 2. In this utility model, the operator steps on the foot pedal, and the traction rope guided by the guide tube and guide wheel pulls the connecting rod, which can drive the storage box to rotate and tilt.

Detailed Implementation

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of an automatic defective product rejection linkage device for a thermistor sorting machine, comprising a sorting machine body 1, a conveyor 4 disposed on the top side of the sorting machine body 1, an electric push rod 14 disposed on the rear side of the sorting machine body 1, a push plate 5 fixedly connected to the drive end of the electric push rod 14, a storage box 2 disposed on the top side of the sorting machine body 1, a baffle 20 rotatably connected to the rear side of the storage box 2, adjacent storage boxes 2 being connected by a connecting rod 3, a guide tube 9 fixedly connected to the front side of the sorting machine body 1, a guide wheel 11 disposed on the top side of the sorting machine body 1, a traction rope 12 disposed at one end of the connecting rod 3, and a foot pedal 10 fixedly connected to the bottom end of the traction rope 12. The traction rope 12 is set inside the guide tube 9 and on the outer wall of the guide wheel 11. A moving table 16 is fixedly connected to one side of the sorting machine body 1. A slide rod is fixedly connected to the inner wall of the moving table 16. A moving plate 17 is set on the outer wall of the slide rod. A reciprocating threaded rod 18 is rotatably connected to the inner wall of the moving table 16. The moving plate 17 is set on the outer wall of the reciprocating threaded rod 18. A second sprocket 19 is fixedly connected to the reciprocating threaded rod 18 and the rear end of the rotating shaft. A first sprocket 13 is fixedly connected to the middle of the rotating shaft and the rear end of the rotating shaft 15. A rotating shaft is rotatably connected to the rear side of the sorting machine body 1. A rotating shaft 15 is set on the rear side of the conveyor 4. The rotating shaft 15 is connected to the rotating shaft through a linkage assembly. Specifically, the thermistor is first placed on the conveyor 4 on the top side of the sorting machine body 1, and is driven by the conveyor 4 to be conveyed to the sorting area. When the thermistor is conveyed to the preset sorting and detection position, the sorting system will quickly complete the performance test and quality judgment of the thermistor. If it is judged to be a defective product, the electric push rod 14 installed on the rear side of the sorting machine body 1 will be activated immediately, and the push plate 5 fixedly connected to its drive end will be pushed towards the conveyor 4, pushing the defective product away from the conveyor 4, ensuring that the defective product falls accurately into the preset storage box 2 on the top side of the sorting machine body 1. The adjacent storage boxes 2 are firmly connected by the connecting rod 3, which can receive multiple sets of defective products at the same time. If it is judged to be a good product, the good product continues to move forward with the conveyor 4. When it moves to the conveyor 4, the good product continues to move forward with the conveyor 4. At the end of conveyor 4, the product enters the guide bucket 6 set at one end of conveyor 4. Since the guide bucket 6 is set on the top side of the collection box 7, and the collection box 7 is placed on the top side of the moving plate 17, the good products will fall smoothly into the collection box 7 under the guidance of the guide bucket 6. During the continuous operation of the device, the rotating shaft connected to the rear side of the sorting machine body 1 always keeps rotating. The rotating shaft is connected to another sprocket 13 fixed at the rear end of the rotating shaft 15 through a sprocket 13 fixed in its middle. The two sprockets 13 are connected by a chain to realize the synchronous linkage between the rotating shaft and the rotating shaft 15. At the same time, a second sprocket 19 is fixed at the rear end of the rotating shaft. The second sprocket 19 is rotatably connected to the rear end of the reciprocating threaded rod 18 of the moving table 16. The other sprocket 19 is also connected to the other sprocket 19 by a chain, so that the power of the rotating shaft can be transmitted to the reciprocating threaded rod 18 through the chain drive, causing the reciprocating threaded rod 18 to rotate synchronously. Since the moving plate 17 is sleeved on the outer wall of the slide rod inside the moving table 16 and is threadedly connected to the reciprocating threaded rod 18, the rotation of the reciprocating threaded rod 18 will be converted into the reciprocating linear movement of the moving plate 17 along the slide rod, thereby driving the storage box 7 on the top side of the moving plate 17 to move synchronously back and forth, ensuring that the storage box 7 can evenly receive good products and avoid uneven accumulation of good products in the storage box 7. When the defective products in the storage box 2 have accumulated to a certain amount and need to be cleaned, the operator can step on the foot pedal 10 below the guide tube 9 set on the front side of the sorting machine body 1. The traction rope 12 connected to the top of the sorting machine moves along the inside of the guide tube 9 and the outer wall of the guide wheel 11 on the top side of the sorting machine body 1. The traction rope 12 pulls the connecting rod 3, which in turn drives the collection box 2 to rotate around its connection point to achieve a tilting action. At this time, the baffle 20 on the rear side of the collection box 2 will open as the collection box 2 rotates, and the defective products will be poured out from the collection box 2. The front side of the sorting machine body 1 is equipped with a moving box 8, which is located below the tilting direction of the collection box 2. The defective products will fall accurately into the moving box 8 for centralized collection. After the moving box 8 is full, the operator can directly move the moving box 8 to transfer and process the defective products. Through the close cooperation and coordinated work of each structure, the continuous sorting of thermistors, automatic rejection of defective products, and classified collection are achieved.

[0019] Reference Figures 2-4 Two sprockets 19 and two sprockets 13 are connected by chains. A movable box 8 is provided on the front side of the sorting machine body 1, and a storage box 7 is provided on the top side of the movable plate 17. A guide bucket 6 is provided at one end of the conveyor 4, and the guide bucket 6 is located on the top side of the storage box 7. Specifically, the mobile box 8 can be equipped with wheels at the bottom to transport defective thermistors. The chain drive structure will be equipped with corresponding protective structures as needed in actual use. The storage box 7 is placed directly on top of the mobile platform 16, and the guide bucket 6 will ensure that good thermistors fall into the storage box 7.

[0020] Working principle: First, the thermistor is conveyed on the conveyor 4 on the top side of the sorting machine body 1. When it reaches a specific position, the electric push rod 14 on the rear side of the sorting machine body 1 will act according to the sorting result. The push plate 5 fixedly connected to its drive end will push out the defective products, ensuring that the defective products fall into the storage box 2. The good products continue to move with the conveyor 4 and finally fall into the storage box 7 on the top side of the moving plate 17 through the guide bucket 6 set at one end of the conveyor 4. During the operation of the device, the rotating shaft rotatably connected to the rear side of the sorting machine body 1 will rotate continuously. The rotating shaft is connected to the rotating shaft 15 through the chain drive between the two sprockets 13 fixed in the middle of the rotating shaft and the rear end of the rotating shaft 15, realizing the linkage between the rotating shaft and the rotating shaft 15. At the same time, the rotating shaft is also connected to the inner wall of the moving table 16 through the chain drive between the two sprockets 19 fixed to the reciprocating threaded rod 18 and the rear end of the rotating shaft. The threaded rod 18 is connected, causing the reciprocating threaded rod 18 to rotate. Since the moving plate 17 is fitted both on the outer wall of the slide rod inside the moving table 16 and on the outer wall of the reciprocating threaded rod 18, the rotation of the reciprocating threaded rod 18 will drive the moving plate 17 to reciprocate along the slide rod, thereby driving the collection box 7 to move to evenly receive good products. In addition, adjacent collection boxes 2 are connected by a connecting rod 3. When it is necessary to collect defective products inside the collection box 2, the operator can step on the sorting machine body 1. The foot pedal 10 below the front guide tube 9 pulls the connecting rod 3 via the traction rope 12. The traction rope 12 moves along the inside of the guide tube 9 and the outer wall of the guide wheel 11 on the top side of the sorting machine body 1, thereby tilting the storage box 2. Due to the rotation of the baffle 20 and the rear side of the storage box 2, the rear end of the storage box 2 opens, and the defective products inside the storage box 2 are poured into the interior of the moving box 8 for collection. This completes the sorting and defective product removal of the thermistors with the help of the entire device.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
