Description

Technical Field

[0001] This utility model relates to the field of logistics sorting technology, and in particular to a non-contact power supply component and a narrow-band linear sorting machine. Background Technology

[0002] In the field of automated material handling such as logistics warehousing and express sorting, narrow-belt linear sorters are widely used for the rapid classification and conveying of various goods due to their high sorting efficiency and stable operation. During operation, the moving sorting unit of this type of sorter requires a continuous supply of electrical energy to drive its movement and complete the sorting action. Therefore, a stable and reliable power supply is one of the key factors ensuring the efficient operation of narrow-belt linear sorters. Currently, existing narrow-belt linear sorters typically use brushes to power the moving sorting unit. Specifically, this involves the brushes mounted on the moving sorting unit maintaining sliding contact with a fixed conductive track to achieve power transmission.

[0003] However, this brush-based power supply method has many insurmountable drawbacks in long-term practical use, seriously affecting the operational stability, service life, and maintenance costs of narrow-strip linear sorting machines. Firstly, because the brush and conductive track are always in mechanical sliding contact, both inevitably experience mechanical wear as the sorting machine continues to operate. This not only significantly shortens the brush's lifespan, requiring frequent brush replacements to ensure power supply efficiency and increasing maintenance frequency and costs, but also causes metal shavings or carbon powder to accumulate on and around the conductive track surface. If not cleaned promptly, this further exacerbates poor contact between the brush and track, potentially leading to short circuits and threatening the safe operation of the sorting machine. Secondly, at high operating speeds, the sliding contact between the brush and track is prone to jumping and increased friction, resulting in unstable contact resistance. This causes fluctuations in the power supply voltage and current, affecting the normal operation of the moving sorting unit's drive motor. This can lead to problems such as sorting unit jamming and inaccurate sorting actions, reducing the overall sorting efficiency and accuracy of the sorting machine. Furthermore, the brush-based power supply method is highly sensitive to environmental conditions. When the sorting environment contains dust, high humidity, or corrosive gases, the conductive rails and brushes are easily corroded or contaminated, further deteriorating contact performance, shortening equipment lifespan, and increasing the probability of equipment failure, thus disrupting normal production and operations. Finally, because the contact area between the brush and the conductive rail always has exposed conductive components, there is a certain risk of electric shock during equipment maintenance or personnel operation, which is detrimental to the personal safety of operators.

[0004] In view of this, a non-contact power supply component and a narrow-band linear sorting machine are proposed. Utility Model Content

[0005] The purpose of this invention is to provide a non-contact power supply component and a narrow-band linear sorting machine, which can achieve stable non-contact power supply.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A contactless power supply component, including A high-frequency cable, which is connected to a controller, is used to generate an alternating magnetic field; A cable clamp, comprising a cable groove and multiple supporting clamps, wherein the high-frequency cable is disposed in the cable groove and the multiple supporting clamps support and hold the cable groove; The power collector includes an electromagnetic induction module and a converter module, which are electrically connected. The electromagnetic induction module is positioned corresponding to the high-frequency cable and is used to obtain induced electrical energy from the alternating magnetic field of the high-frequency cable.

[0007] In a preferred embodiment, the groove is made of rubber or plastic material.

[0008] In a preferred embodiment, the support clamp includes a base plate and a longitudinal plate, the longitudinal plate is disposed on the base plate, the base plate is provided with a fixing through hole, the top of the longitudinal plate is provided with a clamping groove, and the wire groove is clamped in the clamping groove.

[0009] In a preferred embodiment, the clamping groove is provided with a guide boss, and the wire groove is provided with a guide groove arranged along its length direction, and the guide boss is confined in the guide groove.

[0010] In a preferred embodiment, the side of the longitudinal plate is provided with a plurality of slots.

[0011] In a preferred embodiment, a support plate is provided between the longitudinal plate and the bottom plate.

[0012] In a preferred embodiment, the support clamp has a vertical through hole, which includes a first hole segment and a second hole segment. The first hole segment is located below the second hole segment. A supporting member is provided in the vertical through hole. The supporting member includes a supporting rod, a supporting plate, and an elastic pad. The lower end of the supporting rod is connected to the supporting plate. The supporting rod is inserted into the vertical through hole from bottom to top, and its upper end abuts against the groove. The elastic pad is passed through by the supporting rod and is located in the first hole, between the top of the first hole and the supporting plate.

[0013] In a preferred embodiment, the elastic pad is made of rubber or silicone material.

[0014] A narrow-band linear sorting machine includes the aforementioned non-contact power supply component.

[0015] Compared with existing technologies, this invention stably mounts the cable clamps onto the frame of the sorting machine via multiple supporting clamps, placing the cable tray in a preset fixed position. The high-frequency cable is laid and fixed within the cable tray, ensuring a reliable connection between the high-frequency cable and the external controller. The power collector is correspondingly installed on the sorting trolley, maintaining a preset corresponding position between the electromagnetic induction module in the power collector and the high-frequency cable, ensuring stable relative positions and meeting the inductive power extraction requirements. When the components start working, the controller outputs a current of a specific frequency to the high-frequency cable, generating an alternating magnetic field under the influence of the current. Since the electromagnetic induction module corresponds to the high-frequency cable, it is within the range of this alternating magnetic field. According to the principle of electromagnetic induction, the electromagnetic induction module induces electrical energy from the alternating magnetic field. Subsequently, the converter module, electrically connected to the electromagnetic induction module, processes the induced electrical energy, such as converting AC to DC and adjusting the voltage to the rated voltage required by the sorting trolley, ultimately outputting electrical energy that meets the operating requirements of the sorting trolley drive and related electrical components, thereby achieving contactless power supply to the sorting trolley. During the operation of the sorting machine, as the sorting trolley moves along the frame track, it drives the power collector to move synchronously. The electromagnetic induction module always maintains a corresponding position with the fixed high-frequency cable, continuously obtaining induced electrical energy from the alternating magnetic field of the high-frequency cable, ensuring that the sorting trolley can obtain a stable power supply throughout the entire movement process.

[0016] This non-contact power supply component completely eliminates the traditional sliding contact power extraction method of brushes and conductive tracks by using a high-frequency cable to connect with the electromagnetic induction module in the power collector. This effectively avoids wear problems caused by mechanical contact. On the one hand, it eliminates the need for frequent replacement of worn parts, significantly reducing the frequency and cost of equipment maintenance and minimizing the impact of maintenance downtime on sorting efficiency. On the other hand, it also avoids the generation of wear debris, preventing poor contact or short circuits caused by debris accumulation, thus significantly improving the stability and reliability of power supply. Furthermore, due to the absence of mechanical sliding contact, the relative position between the electromagnetic induction module and the high-frequency cable remains stable even at high speeds of the sorting cart. The inductive power extraction process is unaffected by fluctuations in speed, and the voltage and current output by the converter module are stable. This provides continuous and stable power to the drive motor and other electrical components of the sorting cart, effectively preventing problems such as operational jamming and inaccurate sorting actions, ensuring the sorting efficiency and accuracy of the sorting machine. Furthermore, the structural design of this component allows the high-frequency cable to be securely and stably fixed through the cable clamp's groove and support clamp. The power acquisition process eliminates the need for exposed conductive parts, reducing the impact of environmental factors such as dust, humidity, and corrosive gases on the power supply components, extending the component's lifespan, and reducing the probability of failure. It also eliminates the electric shock hazards associated with exposed conductive parts in traditional brush-based power acquisition methods, further enhancing operator safety. Simultaneously, the multi-support clamp design of the cable clamp ensures a secure installation of the high-frequency cable, preventing displacement due to vibrations during sorting machine operation. This further guarantees the stability of power acquisition from the electromagnetic induction module, comprehensively improving the operational reliability and safety of the narrow-band linear sorting machine.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example

[0024] like Figures 1 to 4 As shown, a contactless power supply component includes... High-frequency cable 1, which is connected to the controller, is used to generate an alternating magnetic field; A cable clamp, comprising a cable groove 2 and a plurality of supporting clamps 3, wherein a high-frequency cable 1 is disposed in the cable groove 2 and the plurality of supporting clamps 3 support and hold the cable groove 2; The power collector includes an electromagnetic induction module 12 and a converter module. The electromagnetic induction module 12 and the converter module are electrically connected. The electromagnetic induction module 12 is positioned corresponding to the high-frequency cable 1 and is used to obtain induced electrical energy from the alternating magnetic field of the high-frequency cable 1.

[0025] In this embodiment, a non-contact power supply component stably mounts the cable clamp onto the frame of the sorting machine via its multiple supporting clamps 3, placing the cable tray 2 in a preset fixed position. The high-frequency cable 1 is laid and fixed within the cable tray 2, while ensuring a reliable connection between the high-frequency cable 1 and the external controller. The power collector is correspondingly installed on the sorting cart, and the electromagnetic induction module 12 in the power collector maintains a preset corresponding positional relationship with the high-frequency cable 1, ensuring that the relative position between the two is stable and meets the inductive power collection requirements. When the components start working, the controller outputs a current of a specific frequency to the high-frequency cable 1, which generates an alternating magnetic field under the influence of the current. Since the electromagnetic induction module 12 corresponds to the high-frequency cable 1, it is within the range of this alternating magnetic field. According to the principle of electromagnetic induction, the electromagnetic induction module 12 induces electrical energy from the alternating magnetic field. Subsequently, the converter module electrically connected to the electromagnetic induction module 12 processes the induced electrical energy, such as converting AC to DC and adjusting the voltage to the rated voltage required by the sorting trolley, and finally outputting electrical energy that meets the working requirements of the sorting trolley drive and related electrical components, thereby realizing non-contact power supply to the sorting trolley. During the operation of the sorting machine, when the sorting trolley moves along the frame track, it drives the power collector to move synchronously. The electromagnetic induction module 12 always maintains a corresponding position with the fixed high-frequency cable 1, continuously obtaining induced electrical energy from the alternating magnetic field of the high-frequency cable 1, ensuring that the sorting trolley receives a stable power supply throughout the entire movement process.

[0026] This non-contact power supply component, through the non-contact connection between the high-frequency cable 1 and the electromagnetic induction module 12 in the power collector, completely eliminates the traditional method of power collection via sliding contact between the brush and the conductive track. This effectively avoids wear problems caused by mechanical contact. On the one hand, it eliminates the need for frequent replacement of worn parts, significantly reducing the maintenance frequency and cost of the equipment and minimizing the impact of maintenance downtime on sorting efficiency. On the other hand, it also avoids the generation of wear debris, preventing poor contact or short circuit faults caused by debris accumulation, thus significantly improving the stability and reliability of the power supply. Furthermore, due to the absence of mechanical sliding contact, even in scenarios where the sorting cart is running at high speed, the relative position between the electromagnetic induction module 12 and the high-frequency cable 1 remains stable. The induction power collection process is unaffected by fluctuations in movement speed, and the voltage and current output by the converter module are stable. This provides continuous and stable power to the drive motor and other electrical components of the sorting cart, effectively preventing problems such as operational jamming and inaccurate sorting actions, ensuring the sorting efficiency and accuracy of the sorting machine. Furthermore, the structural design of this component allows the high-frequency cable 1 to be securely and stably fixed through the cable clamp's groove 2 and support clamp 3. The power acquisition process of the power collector does not require exposed conductive parts, which not only reduces the impact of environmental factors such as dust, humidity, and corrosive gases on the power supply components, extending the component's service life and reducing the probability of failure, but also eliminates the electric shock safety hazards caused by exposed conductive parts in the traditional brush power acquisition method, which is more conducive to ensuring the personal safety of operators. At the same time, the multi-support clamp 3 design of the cable clamp ensures that the high-frequency cable 1 is firmly installed, avoiding the displacement of the high-frequency cable 1 due to the vibration of the sorting machine, further ensuring the stability of the electromagnetic induction module 12's power acquisition, and improving the overall operational reliability and safety of the narrow-band linear sorting machine.

[0027] Furthermore, the cable tray 2 is made of rubber or plastic. The use of rubber or plastic in the cable tray 2 serves two purposes: firstly, it utilizes the insulating properties of these materials to prevent leakage risks in the high-frequency cable 1 when it generates an alternating magnetic field during current transmission; secondly, it isolates the cable from the corrosive effects of dust and moisture in the external environment, extending its service life. Thirdly, rubber and plastic possess elasticity and cushioning properties, which can buffer the impact of vibrations on the high-frequency cable 1 during sorting machine operation, reducing cable wear or positional misalignment due to vibration, ensuring a stable correspondence between the high-frequency cable 1 and the electromagnetic induction module 12 of the power collector, thereby maintaining the stability of contactless power supply.

[0028] Furthermore, the support clamp 3 includes a base plate 4 and a longitudinal plate 6. The longitudinal plate 6 is disposed on the base plate 4, and the base plate 4 has a fixing through hole 5. The top of the longitudinal plate 6 has a clamping groove 7, in which the wire groove 2 is clamped. The support clamp 3 forms a stable support and clamping structure through the structural cooperation between the base plate 4 and the longitudinal plate 6. The fixing through hole 5 on the base plate 4 allows fasteners such as bolts and screws to pass through the through hole, firmly installing the entire support clamp 3 on the frame of the sorting machine. This ensures that the support clamp 3 will not shift or loosen due to equipment vibration during the operation of the sorting machine, providing a foundation for the stable laying of the high-frequency cable 1. The clamping groove 7 at the top of the vertical plate 6 is adapted to the shape of the wire groove 2, which can accurately and tightly clamp the wire groove 2 in the groove, preventing the wire groove 2 from falling off or shifting laterally in the vibration environment of the sorting machine. This ensures that the high-frequency cable 1 in the wire groove 2 is always in the preset position, thereby ensuring that the relative position between the electromagnetic induction module 12 on the power collector and the high-frequency cable 1 is stable, meeting the position requirements required for inductive power collection, and avoiding the problem of unstable acquisition of inductive power due to position deviation.

[0029] Furthermore, the clamping groove 7 is provided with a guide boss 16, and the wire groove 2 is provided with a guide groove arranged along its length. The guide boss 16 is confined within the guide groove. The guide boss 16 in the clamping groove 7 and the guide groove on the wire groove 2 cooperate, allowing the wire groove 2 to be pushed along the cooperation direction during installation, achieving precise guidance, preventing the wire groove 2 from being misaligned during installation, and improving installation efficiency. During operation, the guide boss 16 limits the guide groove, restricting the rotation of the wire groove 2.

[0030] Furthermore, the side of the longitudinal plate 6 is provided with multiple slots 8. While ensuring that the supporting strength of the longitudinal plate 6 is sufficient to stably clamp the wire groove 2, the amount of raw materials required for manufacturing the longitudinal plate 6 can be greatly reduced, directly reducing the material cost and production cost of the support clamp 3.

[0031] Furthermore, a support plate 9 is provided between the longitudinal plate 6 and the bottom plate 4. The addition of the support plate 9 between the longitudinal plate 6 and the bottom plate 4 can construct a triangular stable support structure, which can significantly improve the overall bending and deformation resistance of the support clamp 3.

[0032] Furthermore, the support clamp 3 is provided with a vertical through hole, which includes a first hole segment 10 and a second hole segment 11. The first hole segment 10 is located below the second hole segment 11. A supporting member is provided in the vertical through hole. The supporting member includes a supporting rod 13, a supporting plate 14, and an elastic pad 15. The lower end of the supporting rod 13 is connected to the supporting plate 14. The supporting rod 13 is inserted into the vertical through hole from bottom to top, and its upper end abuts against the wire groove 2. The elastic pad 15 is passed through by the supporting rod 13 and is located in the first hole, between the top of the first hole and the supporting plate 14. The vertical through hole of the support clamp 3, through the stepped structure of the first hole segment 10 and the second hole segment 11, provides precise installation and movement space for the supporting member. When the support clamp 3 is not fixed, the elastic pad 15 in the first hole section 10 is in a naturally relaxed state. Its elastic restoring force pushes the abutment piece 14 downward, thereby driving the abutment rod 13 downward along the through hole, causing the upper end of the abutment rod 13 to disengage from the wire groove 2 and release the clamping constraint. In this state, the support clamp 3 can slide freely along the wire groove 2 to adjust its position. The spacing calibration of multiple support clamps 3 can be completed without frequent disassembly and assembly, greatly simplifying the installation process and improving construction efficiency. It is especially suitable for the long-distance laying requirements of high-frequency cables 1 on the sorting machine frame. After the support clamp 3 is secured to the frame through the through hole 5 of the base plate 4, the external fastening force is transmitted to the vertical through hole through the base plate 4, compressing the elastic pad 15 in the first hole section 10, causing the elastic pad 15 to deform and accumulate elastic potential energy. Under the pressure, the abutment plate 14 moves upward, driving the abutment rod 13 to move upward along the through hole, with its upper end tightly abutting the bottom of the wire groove 2. With the help of the pre-tightening force of the elastic pad 15, the abutment rod 13 forms a continuous and stable upward pressure, firmly fixing the wire groove 2 in the clamping groove 7. Combined with the limiting effect of the guide boss 16 and the guide groove, the relative position of the wire groove 2 and the support clamp 3 is locked. This elastic pre-tightening structure can adapt to the small dimensional deviations of the wire groove 2, and when the sorting machine vibrates during operation, the elastic pad 15 can play a buffering role, absorbing vibration energy and avoiding the positional loosening caused by rigid impact between the abutment rod 13 and the wire groove 2, ensuring that the high-frequency cable 1 is always in the preset position and ensuring the stable power supply of the electromagnetic induction module 12 of the power take-off device.

[0033] Furthermore, the elastic pad 15 is made of rubber or silicone material. Example
