Description

Technical Field

[0001] This invention relates to the field of conveyor belt technology, specifically a conductive TPU lightweight conveyor belt. Background Technology

[0002] Conveyor belts, as core components of material handling systems in modern industrial production, are widely used in electronics, food, logistics, and light manufacturing. Their main function is to achieve automated and continuous material transport, thereby significantly improving production efficiency and reducing labor costs. With the continuous upgrading of industrial technology, the production environment places higher demands on the performance of conveyor belts, especially in industries sensitive to static electricity, such as electronic components, semiconductor packaging, and precision instrument manufacturing. Conveyor belts made of ordinary materials are no longer sufficient to meet production needs. Conductive-grade TPU (thermoplastic polyurethane) conveyor belts, with their excellent physical and mechanical properties, good wear resistance, and unique antistatic discharge capabilities, can effectively prevent static electricity buildup from damaging precision products. They are also easy to clean and maintain, thus gradually becoming the preferred material in high-end precision conveying applications.

[0003] However, existing technologies, such as the patent with publication number CN116513705A, which proposes an anti-static conveyor system for industrial automated production workshops, can reduce collisions and static electricity during the transmission of electronic components through transfer belts and synchronization components, but still have obvious structural defects. First, the transfer belt structure in this prior art mainly focuses on buffering during material transfer and does not disclose the high-precision correction mechanism required for the conveyor belt itself to deviate during long-term operation. It lacks the ability to monitor and fine-tune the deviation of the conveyor belt edge in real time, making it difficult to ensure continuous and stable conveying accuracy. Second, although this prior art mentions buffering and vibration reduction, its cleaning methods mainly rely on specific airflow or structural coordination, lacking a linkage cleaning component that can work in conjunction with the tensioning mechanism. It cannot adaptively adjust the cleaning contact area according to changes in conveyor belt tension, making it difficult to thoroughly remove tiny dust and fibers from the surface of the conductive TPU conveyor belt. Furthermore, the functional components in the prior art are mostly independently set or simply connected by transmission, lacking the deep mechanical linkage formed by the guide plate, moving frame and other components between the correction component, tensioning component and cleaning component in this application. This results in insufficient overall structural compactness of the equipment and low efficiency of collaborative operation. Therefore, a conductive TPU lightweight conveyor belt is needed to solve the existing shortcomings. Summary of the Invention

[0004] Technical problems to be solved Existing conveyor belt equipment suffers from poor conveying stability, low cleaning efficiency, and poor structural coordination due to the lack of a high-precision correction mechanism, the inability of the cleaning mechanism to adapt to changes in tension, and the lack of deep linkage and coordination between various components.

[0007] Furthermore, the correction element includes: A rotating column is fixedly connected to the bottom center of the alignment frame and movably engages with the base plate. The rotating column is configured to rotate along the axis of the base plate and move longitudinally to provide multi-degree-of-freedom adjustment capability.

Each guide block has a fixed return spring in its internal cavity to provide elastic restoring force. A pair of guide rods are fixedly connected to the bottom of the correction frame and extend into the inner cavity of the guide block on the corresponding side and are movably engaged with it. The ends of the guide rods abut against the reset spring to form an elastic buffer mechanism. A control element, disposed on the base plate, is configured to control the rotation of the alignment frame around the rotating column, and to cause the two guide blocks to rotate synchronously within the guide groove about the axis of the rotating column.

[0008] Furthermore, a pair of sliding grooves are provided on the base plate; The control component includes: A pair of control frames are symmetrically distributed around the axis of the rotating column as the origin.

A guide rod is fixedly connected to another of the slide grooves, and the guide rod movably passes through both of the sliders; A servo motor is fixedly connected to the base plate, and its output end is connected to the end of the drive rod to provide rotational power.

[0009] Furthermore, the tensioning assembly includes: A pair of tensioning suction tubes are disposed between the two support frames, and their axes are perpendicular to the edge of the conveyor belt body. The tensioning suction tubes make rolling contact with the surface of the conveyor belt body, thereby achieving the tensioning function while assisting in cleaning. The movable frame is slidably connected to the inner side of each of the support frames, and the end of the tensioning adsorption tube moves through the movable frame on the adjacent side to achieve position adjustability. The movable frame is slidably connected to the inner side of each of the support frames, and the movable frame is located at the bottom of the movable frame; Guide plates are fixedly connected to both sides of the correction frame, and the guide plates movably pass through the inner side of the movable frame to realize the linkage between the correction and tensioning mechanisms. The tensioning element, disposed on the support frame, is configured to control the moving frame and the moving frame to move closer or further apart from each other, so as to adjust the longitudinal distance between the tensioning suction tube and the straightening wheel, thereby adjusting the tension of the conveyor belt body.

[0010] Furthermore, the tensioning element includes: Three limiting rods are provided. One of the limiting rods is fixedly connected to both sides of the inside of the support frame, and the other is fixedly connected to one side of the inside of the support frame. The limiting rods move sequentially through the end of the movable frame and the end of the movable frame to ensure the linearity and stability of the movement. An adjusting rod is rotatably connected to the inner side of one of the support frames. The adjusting rod has a set of symmetrical threads. The adjusting rod passes through the end of the movable frame and the end of the movable frame, and is threadedly engaged with the movable frame and the movable frame.

[0011] Furthermore, the tensioning element also includes: Servo motor 2 is fixedly connected to the top of one of the support frames, and its output end is connected to the top of the adjustment rod for transmission.

[0012] Furthermore, the tensioning adsorption tube has a hollow structure with an open end. A circular array of elongated adsorption grooves are provided on it to increase the adsorption area and adhere to the surface of the conveyor belt body. The small debris attached to the surface of the conveyor belt body is adsorbed by the negative pressure principle.

[0013] Furthermore, the cleaning component includes: A pair of cleaning wheels are movably connected between the two movable frames via a rotating shaft, and the brushes on the surface of the cleaning wheels abut against the surface of the conveyor belt body; Synchronous wheel one, each end of the tensioning adsorption tube is fixedly connected to the synchronous wheel one; Synchronous wheel two: Each of the cleaning wheels has a synchronous wheel two fixedly connected to its shaft, and the diameter of the synchronous wheel two is smaller than the diameter of the synchronous wheel one; A timing belt is fitted around the outside of timing pulley one and timing pulley two to form a transmission structure, so that when the tensioning suction tube rotates, it drives the cleaning wheel to rotate through the timing belt, forming a linkage cleaning.

[0014] Furthermore, the cleaning component also includes: A fixed frame is fixedly connected to one of the movable frames; The negative pressure pipe, in a Y-shaped structure, is fixedly connected to the fixed frame; The two ends of the negative pressure tube are rotatably connected to the ends of the tensioning adsorption tube, and the other end of the negative pressure tube is connected to an external negative pressure device.

[0015] Compared with existing technologies, this conductive TPU lightweight conveyor belt has the following advantages: I. This invention, through the linkage between the tensioning component and the cleaning component, uses the tensioning suction tube as a power source to drive the cleaning wheel to rotate. The diameter of the second synchronous wheel is designed to be smaller than that of the first synchronous wheel. By utilizing the transmission ratio principle, the cleaning wheel obtains a rotation speed higher than that of the conveyor belt, thereby generating strong mechanical friction to brush off stubborn dirt from the surface. At the same time, the suction groove on the tensioning suction tube uses the principle of negative pressure to instantly suck away the dirt, thus achieving efficient deep cleaning while adjusting the tension.

[0016] Second, this invention sets up a mechanical linkage structure between the correction component and the tensioning component, and uses a guide plate that moves through the inside of the moving frame. This allows the moving frame to provide support when the correction frame deflects, while the moving frame can drive the correction frame, the rotating column, and the guide rod to move synchronously longitudinally through the guide plate when adjusting the tension. This achieves complementary spatial positions and adaptive following of the correction and tensioning actions, avoiding damage to the overall structural stability caused by a single action.

[0017] Third, this invention uses conductive TPU material to make the conveyor belt body and combines it with a linkage cleaning component to efficiently remove surface dust. This not only gives full play to the excellent wear and oil resistance of TPU material, but more importantly, it can effectively discharge the static electricity generated by friction during the conveying process. It is particularly suitable for production scenarios that are sensitive to static electricity, such as electronic components and lithium battery electrodes, thereby improving the production yield and equipment safety.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-10 As shown, the present invention provides a technical solution: a conductive TPU lightweight conveyor belt. The device is installed on the ground of an industrial production line and is mainly used for automated material conveying. It is particularly suitable for production environments with high requirements for anti-static and cleanliness. The conveyor belt mainly includes a mounting frame 1, a conveyor belt body 2, a base plate 3, a correction sensor 4, a correction component 5, a support frame 6, a tensioning component 7, and a cleaning component 8.

[0022] It is particularly important to note that the conveyor belt body 2 in this embodiment is made of conductive TPU (thermoplastic polyurethane elastomer) material. This material not only inherits the excellent wear resistance, oil resistance, and high elasticity of TPU, but also has good conductivity. In production scenarios that are sensitive to static electricity, such as electronic components and semiconductor packaging, conductive TPU material can effectively discharge static electricity generated by friction during the conveying process, preventing static electricity from damaging precision chips or attracting fine dust, thereby greatly improving the production yield. For example, in the scenario of lithium battery electrode conveying, this device can provide a static-free and pollution-free conveying environment; on the production line of precision electronic connectors, it can ensure that components are not affected by static electricity during the conveying process.

[0023] Mounting frame 1 is placed on the ground as an overall support base. The conveyor belt body 2 is rotatably mounted on the top of mounting frame 1. The edge of the conveyor belt body 2 is designed to be recessed into the inside of mounting frame 1. This structure can effectively prevent materials from getting stuck in the edge gaps during the conveying process. A base plate 3 is fixedly installed below the middle position of mounting frame 1. The key correction component 5 is supported on the base plate 3. A pair of correction sensors 4 are also symmetrically arranged on mounting frame 1. These sensors can detect the deviation of the edge of the conveyor belt body 2 in real time. Once deviation is detected, a position deviation signal is immediately generated to provide action commands for the correction component 5.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the belt alignment component 5 is the core component that ensures the stable operation of the conveyor belt. Its main body is a belt alignment frame 501 rotatably mounted on the top of the base plate 3. A pair of belt alignment wheels 502 are movably connected to both sides of the belt alignment frame 501 via rotating shafts. These two belt alignment wheels 502 maintain rolling contact with the inner side of the conveyor belt body 2, thus guiding the direction of the conveyor belt. A rotating column 503 is fixedly connected to the center of the bottom of the belt alignment frame 501. This rotating column 503 is movably engaged with the base plate 3, allowing it to rotate along the axis of the base plate 3. It can also move longitudinally, which provides the alignment frame 501 with multi-degree-of-freedom adjustment capability. A pair of guide grooves 9 are opened through the base plate 3. Guide blocks 504 are slidably connected in the guide grooves 9. A reset spring 506 is fixedly installed in the internal cavity of each guide block 504. At the same time, a pair of guide rods 505 are fixedly connected to the bottom of the alignment frame 501. These guide rods 505 extend into the internal cavity of the guide block 504 and move in cooperation with it. The ends abut against the reset springs 506 to form an elastic buffer mechanism.

[0025] To drive the alignment frame 501 and ensure adjustment accuracy, a control component is provided on the base plate 3. The base plate 3 also has a pair of sliding grooves 10. The control component includes a pair of control frames 507 symmetrically distributed around the axis of the rotating column 503. A slider fixedly connected to the end of each control frame 507 slides in cooperation with the sliding groove 10. A drive frame 508 is also fixedly connected to the end of each control frame 507. This drive frame 508 is movably sleeved on the outside of the guide rod 505 to transmit power. In the drive structure, a drive rod 509 rotatably disposed within the sliding groove 10 plays a crucial role. This drive rod 509 employs… A high-precision lead screw (such as a ball screw) has a set of symmetrically distributed threaded sections on its shaft. The drive rod 509 passes through the slider and engages with its thread. When the servo motor 511 fixed on the base plate 3 is started, its output end drives the high-precision lead screw drive rod 509 to rotate. Utilizing the high-precision characteristics of the lead screw transmission, the two sliders can move in opposite directions. In turn, the drive frame 508 drives the guide rod 505 and the correction frame 501 to deflect, achieving precise correction control. A guide rod 510 is also fixedly connected in the slide groove 10, which moves through the slider to play an auxiliary guiding and supporting role.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the tensioning assembly 7 is positioned between two support frames 6, which are fixedly connected to both sides of the mounting frame 1 and fixedly connected to the side of the base plate 3 at their bottom, forming a stable frame. The tensioning assembly 7 includes a pair of tensioning suction tubes 701 with their axes perpendicular to the edge of the conveyor belt body 2. These tubes roll in contact with the surface of the conveyor belt body 2. The tensioning suction tubes 701 are mounted on a movable frame 702, which is slidably connected to the inside of the support frames 6. The movable frame 703 is also slidably connected to the inside of the support frames 6 and located at the bottom of the movable frame 702. Guide plates 704 are fixedly connected to both sides of the correction frame 501, and these guide plates 704 move through the inside of the movable frame 703. This achieves a precise linkage between the correction assembly 5 and the tensioning assembly 7. When the correction component 5 is working, the correction frame 501 deflects, and the guide plate 704 rotates around the rotating column 503. At this time, the guide plate 704 is in active cooperation with the inner side of the moving frame 703. The moving frame 703 plays the role of supporting the guide plate 704, ensuring the stability of the correction frame 501 during the deflection process. When the tensioning assembly 7 is working, the moving frame 703 moves longitudinally. The moving frame 703 drives the correction frame 501 to move longitudinally through the guide plate 704, so that the rotating column 503 and the guide rod 505 both move longitudinally. This changes the height position of the correction wheel 502 while adjusting the tension, thus realizing the spatial position linkage between tensioning and correction.

[0027] The tensioning component is used to adjust the tension of the conveyor belt. It includes three limiting rods 705, which are arranged inside the support frame 6 and move sequentially through the ends of the movable frame 702 and the movable frame 703 to ensure the linearity and stability of the movement. The adjusting rod 706, which is rotatably connected to the inside of the support frame 6, has a set of symmetrical threads and engages with the movable frame 702 and the movable frame 703. The adjusting rod 706 is also made of high-precision lead screw to meet the high-precision requirements of tension adjustment. When the servo motor 707 fixed at the top of the support frame 6 is started, it drives the high-precision adjusting rod 706 to rotate, thereby driving the movable frame 702 and the movable frame 703 to move, controlling the movable frame 702 to move closer or further away from each other, adjusting the longitudinal distance between the tension suction tube 701 and the correction wheel 502, and realizing the precise adjustment of the tension of the conveyor belt body 2.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the cleaning component 8 is another highlight of the device. It works in conjunction with the tensioning component 7 to achieve a highly efficient "tensioning and cleaning simultaneously" operation mode. The tensioning suction tube 701 is designed as a hollow structure with one end open. A circular array of elongated suction grooves 11 are formed through the tube wall. These suction grooves 11 adhere to the surface of the conveyor belt body 2, using the principle of negative pressure to adsorb fine debris adhering to the conveyor belt surface, achieving deep cleaning. A pair of cleaning wheels 801 are movably connected between two movable frames 702 via a rotating shaft. The brushes on their surfaces abut against the surface of the conveyor belt body 2. For transmission, a synchronous pulley 802 is fixedly connected to the end of the tensioning suction tube 701. A second synchronous wheel 803 is fixedly connected to the shaft of the cleaning wheel 801. The diameter of the second synchronous wheel 803 is designed to be smaller than that of the first synchronous wheel 802. This design utilizes the transmission ratio principle, which makes the rotation speed of the cleaning wheel 801 much higher than that of the tensioning adsorption tube 701. When the tensioning adsorption tube 701 rotates with the conveyor belt, the high-speed rotating cleaning wheel 801 can brush the surface of the conveyor belt at a faster linear speed. Through the transmission of the synchronous belt 804, a strong mechanical friction force is generated, which effectively brushes off the stubborn dirt adhering to the surface of the conductive TPU conveyor belt. The brushed dirt is then sucked away by the adjacent tensioning adsorption tube 701 through negative pressure, which greatly improves the cleaning efficiency.

[0029] It is worth noting the synchronized movement of the tensioning assembly 7 and the cleaning assembly 8 in space: when the tensioning assembly 7 is working, the moving frame 702 drives the cleaning wheel 801 and the tensioning suction tube 701 to move synchronously. Specifically, when the moving frame 702 drives the tensioning suction tube 701 closer to the correction wheel 502 (i.e., further tensioning the conveyor belt), the surface contact area between the cleaning wheel 801 and the conveyor belt body 2 will decrease accordingly; conversely, when the tensioning suction tube 701 moves away from the correction wheel 502 (i.e., loosening the conveyor belt), the surface contact area between the cleaning wheel 801 and the conveyor belt body 2 will increase. This linkage design allows the cleaning wheel 801 to adaptively adjust the contact area according to the tension of the conveyor belt, ensuring good cleaning results under different tension levels.

[0030] To maintain the negative pressure adsorption function, the cleaning component 8 also includes a fixed frame 805 fixed on the movable frame 702, and a negative pressure tube 806 with a Y-shaped structure. The two connecting ends of the negative pressure tube 806 are rotatably connected to the end of the tension adsorption tube 701 to ensure that the tension adsorption tube 701 remains sealed when it moves or rotates. The other connecting end is connected to an external negative pressure device to continuously provide adsorption power.

[0031] Working process: First, based on the characteristics of the conveyed material, the system automatically or manually sets the tension, servo motor 2 707 starts, and through the rotation of the high-precision adjusting rod 706, it drives the moving frame 702 to move, applying precise tension to the conveyor belt body 2. At the same time, the cleaning wheel 801 adaptively adjusts the contact area. Subsequently, the external motor and negative pressure equipment start, and the conveyor belt runs. If the deviation sensor 4 detects a deviation signal, servo motor 1 511 starts, and through the high-precision driving rod 509, it drives the deviation frame 501 to deflect. At this time, the deviation wheel 502 guides the conveyor belt to reset, and the tensioning component 7 adaptively follows through the guide plate 704. At the same time, the cleaning wheel 801 rotates at high speed under the linkage, continuously brushing away dirt on the surface of the conveyor belt, which is then sucked away by the tension suction tube 701, completing all-weather, automated high-precision conveying and cleaning operations.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
