Description

Technical Field

[0001] This utility model relates to the field of cutting, specifically a waste cutting device suitable for high-speed chip assembly production lines. Background Technology

[0002] High-speed surface mount technology (SMT) production lines are core equipment in the electronics manufacturing industry, used to quickly and accurately mount microelectronic components onto the surface of PCB boards, ultimately forming functional electronic modules. During SMT assembly, components are typically loaded onto feeders in roll or reel form. These feeders, along with their carrier tapes or cover tapes, generate a significant amount of waste (such as carrier tape scraps, cover tape waste, and encapsulation film residue) after component delivery. For example, with common 8mm or 12mm pitch carrier tapes, each roll can be hundreds of meters long, resulting in continuous strip-shaped waste after mounting. Some irregularly shaped components or specially packaged devices may use more complex packaging materials (such as anti-static films, multi-layer composite carrier tapes, etc.), resulting in more complex and resilient waste structures. If this waste is not removed from the production line in a timely and efficient manner, it will lead to equipment wear, decreased precision, and reduced production efficiency.

[0003] To address the aforementioned issues, some waste treatment devices already exist in existing technologies, such as waste collection systems based on vacuum adsorption or processing devices that use mechanical traction combined with centralized winding. However, these systems are typically bulky, costly, and have strict limitations on the material and size of the waste, making them less versatile for small-batch, multi-variety production scenarios. Furthermore, if the waste contains sticky residues, it may lead to adsorption failure or winding slippage, reducing the reliability of waste treatment.

[0004] Therefore, developing a waste cutting device specifically for high-speed chip assembly lines is of significant engineering value and market demand for improving the automation level of electronic manufacturing lines, ensuring production continuity and yield, and reducing overall costs.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to preferred embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 5A waste cutting device suitable for high-speed chip assembly lines includes a device body 1. The inner cavity of the device body 1 is divided into a cutting cavity 2 and a storage cavity 3 from top to bottom, and the cutting cavity 2 and the storage cavity 3 are in a connected state. A waste inlet 5 adapted to the waste generated by the high-speed chip assembly line is provided at the top of one end of the cutting cavity 2. In use, the strip-shaped waste generated by the high-speed chip assembly line can enter the inner cavity of the device body 1 through the waste inlet 5. A waste conveying assembly is provided above the waste inlet 5. The waste conveying assembly includes a set of conveying rollers 8 movably connected to the top of the device body 1 and a first driving structure 17 for driving the conveying rollers 8 to rotate. The two conveying rollers 8 are distributed vertically. A pressure sensor 16 is provided on the outer ring of the middle of the conveying rollers 8. In use, the waste conveying assembly is used to convey the strip-shaped waste. During the conveying process, the tightness of the strip-shaped waste can be detected by the pressure sensor 16.

[0017] In Embodiment 1, a fixed rod is provided on the top of the device body 1. One conveying roller 8 is movably connected to the fixed rod. The top of the fixed rod is connected to a lifting rod through a high-precision ball screw pair. The other conveying roller 8 is movably connected to the lifting rod. Under the action of the high-precision ball screw pair, the distance between the lifting rod and the fixed rod can be changed, thereby changing the distance between the two conveying rollers 8. When this application is used, the waste conveying assembly can adapt to strip waste of various thicknesses, improving the practicality of this application. Furthermore, the first drive structure 17 is a servo motor, which is connected to the conveying roller 8 through a coupling and a reducer.

[0018] A guide plate 18 is provided below the waste feed inlet 5. The guide plate 18 is located directly below the conveyor roller 8. The guide plate 18 can guide the strip of waste moving at the top of the inner cavity of the device body 1, so that the strip of waste is in a vertical moving state.

[0019] Below the waste tensioning assembly is a waste cutting assembly, which is used to cut strip waste to facilitate the conveying and collection of strip waste. The waste cutting assembly includes a lifting plate 6, which is connected to the top of the device body 1 through a lifting structure 21. Under the action of the lifting structure 21, the height of the lifting plate 6 can be changed, thereby changing the height of the waste cutting assembly.

[0020] The lifting plate 6 is provided with a through groove 19, which is located directly below the waste inlet 5. Under the action of gravity, the strip waste can pass through the waste inlet 5 and the through groove 19 in sequence, and finally enter the storage cavity 3.

[0021] A positioning plate 22 is provided on one side of the top of the through groove 19. The positioning plate 22 is located directly below the conveying roller 8. A moving plate 7 is connected to the other side of the top of the through groove 19 through a first linear moving structure 27. A waste cutting blade 25 is provided in the middle of the side of the moving plate 7 near the positioning plate 22. A connecting rod 20 is movably connected to the top and bottom of the moving plate 7. A waste fixing block 23 is connected to the end of the connecting rod 20 away from the moving plate 7. The waste fixing block 23 is connected to the moving plate 7 through a spring 26. Through the first linear moving structure 27, the first linear moving structure 27 can drive the moving plate 7 connected to it to move. The moving plate 7 drives the waste cutting blade 25 and the waste fixing block 23 connected to it to move, so that the distance between the waste cutting blade 25 and the waste fixing block 23 and the positioning plate 22 changes. When the waste fixing block 23 and the positioning plate 22 clamp and fix the strip of waste located between the waste inlet 5 and the through groove 19, when the first linear moving structure 27 drives the moving plate 7 to continue moving, the moving plate 7 compresses the waste fixing block 23 through the spring 26, improving the reliability of the waste fixing block 23 in clamping the strip of waste. The moving plate 7 can drive the waste cutting blade 25 to cut the strip of waste. The positioning plate 22 is provided with a groove 24 adapted to the waste cutting blade 25 on the side near the waste cutting blade 25. The groove 24 can eliminate the cutting blind zone and ensure that the blade of the waste cutting blade 25 can fully act on the waste, ensuring that the waste is completely cut off.

[0022] Furthermore, during the cutting process, the lifting structure 21 drives the lifting plate 6 to move downwards. The lifting plate 6, through the waste fixing block 23 and the positioning plate 22, drives the strip of waste downwards, ensuring the stability of the strip of waste conveying. After cutting, the first linear moving structure 27 drives the moving plate 7 to move in the opposite direction, releasing the clamping and fixing of the strip of waste and resetting it. The cut strip of waste falls into the storage cavity 3 under the action of gravity. The uncut strip of waste at the top of the device body 1 continues to be conveyed downwards under the action of the waste conveying assembly. The controller of this application can control the waste cutting assembly to cut the waste based on a preset cycle or when the pressure detected by the pressure sensor 16 is not within a preset threshold.

[0023] The guide plate 18, the positioning plate 22, and the conveying roller 8 are all located on the same vertical plane near the waste cutting blade 25, so that when this application is used, the strip of waste located between the waste inlet 5 and the through groove 19 is in a vertical state, which facilitates the guidance and fixation of the waste.

[0024] In Example 2, both the first linear movement structure 27 and the lifting structure 21 are cylinders. The cylinder model and specifications can be set according to requirements and are not limited here.

[0025] A dust-collecting plate 4 is provided at the other end of the cutting chamber 2. An exhaust fan 11 and an air filter 12 are provided on the exterior of the device body 1. The air inlet of the exhaust fan 11 is connected to the air outlet of the dust-collecting plate 4 via an exhaust pipe 14, and the air outlet of the exhaust fan 11 is connected to the air inlet of the air filter 12 via an exhaust pipe 15. By providing the exhaust fan 11, when the exhaust fan 11 is working, it can remove the dust-laden air from the cutting chamber 2, preventing dust leakage during the cutting of strip waste materials. The dust-laden air enters the air filter 12 through the exhaust pipe 15, where it intercepts impurities in the air, and clean air is discharged through the air outlet of the air filter 12. The air filter 12 adopts existing technology and can filter impurities in the air based on a filter screen. Its specific structure and principle are publicly available technologies and will not be further described here.

[0026] A belt conveyor structure 9 is provided at the bottom of the storage cavity 3, and a sealing door 10 is detachably connected to one side of the storage cavity 3. In use, the belt conveyor structure 9 transports waste material from the outlet end of the cutting cavity 2 to the outlet end of the storage cavity 3, increasing the storage capacity of the storage cavity 3. When it is necessary to clean up the collected belt-shaped waste, the user opens the sealing door 10 and uses the belt conveyor structure 9 to transport the waste material to the outside, improving waste cleaning efficiency. The belt conveyor structure 9 adopts existing technology, and its specific structure and operation will not be described in detail here.

[0027] In addition, a controller 13 is provided on the device body 1. All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, a suitable controller 13 is selected to meet the control requirements. For specific connections and control sequences, please refer to the following description. The electrical connections between the various electrical components are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0028] In summary: When using this waste cutting device suitable for high-speed chip assembly lines, the user sets the device at a suitable position on the high-speed sheet metal production line and uses the waste conveying assembly to transport the belt waste, so that the belt waste enters the device body 1. The belt waste enters the storage cavity 3 through the waste inlet 5 and the through groove 19. The belt waste moves between the positioning plate 22, the waste positioning block 28, and between the directional guide roller 23 and the moving guide roller 19. The controller 13 of this application controls the waste cutting assembly to cut the belt waste in the device body 1 based on a preset cycle or when the data collected by the pressure sensor 16 is lower than a preset threshold. The cutting steps are as follows: The first linear moving structure 27 drives the connected moving plate 7 to move, and the moving plate 7 drives the connected waste cutting blade 25 and waste fixing block 23 to move. After the waste fixing block 23 and positioning block 22 clamp and fix the strip waste, the lifting structure 21 drives the lifting plate 6 to move down, which in turn drives the strip waste to move down stably, thereby ensuring the stability of the strip waste conveying. The first linear moving structure 27 drives the moving plate 7 to continue moving. The moving plate 7 can squeeze the waste fixing block 23 through the spring 26 to improve the grip of the waste fixing block 23 on the strip waste. For reliable clamping, the moving plate 7 can drive the waste cutting blade 25 to cut the strip waste. After cutting, the first linear moving structure 27 drives the moving plate 7 to move in the opposite direction. The moving plate 7 drives the waste fixing block 23 and the waste cutting blade 25 to move in the opposite direction until the clamping and fixing of the strip waste is released. The cut strip waste falls into the storage cavity 3 under the action of gravity. The uncut strip waste at the top of the device body 1 continues to be conveyed downward under the action of the waste conveying assembly. The lifting structure 21 drives the lifting plate 6 to reset, which facilitates the reuse of the waste cutting assembly.
