Description

Technical Field

[0001] This invention relates to the field of new energy vehicle production technology, specifically to a conveyor belt for new energy vehicle production components. Background Technology

[0002] With the profound adjustment of the global energy structure and the continuous pressure of environmental protection policies, the new energy vehicle industry has entered a golden age of explosive growth, and the degree of automation in its industrial chain has become an important indicator for measuring core competitiveness. In the production process of new energy vehicles, the production processes of key components such as drive motor housings, power battery module frames, and high-voltage electronic control unit housings place almost stringent requirements on the transportation links: First, these components are mostly aluminum alloy die-cast parts or integrated electronic components with extremely sensitive surfaces. Even minor scratches or bumps can lead to the scrapping of the entire part or failure of sealing performance; Second, the electromagnetic environment inside the new energy workshop is extremely complex due to the presence of a large number of high-frequency welding, variable frequency speed regulation, and power electronic conversion equipment. Traditional sensor signals are easily affected by harmonic interference, resulting in malfunctions and disrupting the production cycle.

[0003] However, an examination of existing material handling technologies reveals the following significant drawbacks: First, most traditional conveyor equipment employs chain drive structures. The meshing between the chain and sprockets not only generates significant high-frequency noise but also requires frequent lubrication. This oil splatter easily contaminates and pollutes precision components in new energy applications, failing to meet cleanroom management standards. Furthermore, the risk of chain breakage due to mechanical wear directly threatens the continuity of the production line. Second, existing feeding and discharging mechanisms often lack effective kinetic energy management. The moment components transition from stationary to moving motion, or slip from the belt end to the collection area, significant instantaneous impact forces are generated. Existing metal tracks cannot provide the necessary elastic cushioning, resulting in a high rate of surface scratches on components. Third, current conveyor belt support structures are mostly simple metal frames. When carrying heavy battery packs, the lower bearing section of the belt is prone to bending and deformation, leading to an exponential increase in frictional resistance. This not only increases the energy burden on the motor but also causes component positioning failure due to belt slippage. Fourth, in terms of electrical wiring, conventional conveyors lack a systematic cable management scheme, control lines and power lines are mixed together, and sensors lack targeted anti-interference design and physical protection, which often leads to signal deviations such as missed detections and over-detections under actual working conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a conveyor belt for new energy vehicle manufacturing components, which can improve the surface quality protection of precision components and provide a high degree of human-machine interaction and operational transparency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt for the production of new energy vehicle components, comprising: The system includes a bottom load-bearing base frame, a vertical support frame located above the bottom load-bearing base frame, a horizontal U-shaped conveyor trough plate installed on top of the vertical support frame, a rotating bearing positioning seat fixed at the front end of the horizontal U-shaped conveyor trough plate, an active rubber-coated drive roller spanning the inside of the horizontal U-shaped conveyor trough plate via the rotating bearing positioning seat, a direct-drive reduction motor installed on one side of the shaft end of the active rubber-coated drive roller, a tension adjustment support located at the other end of the horizontal U-shaped conveyor trough plate, a passive following roller installed at the rear of the horizontal U-shaped conveyor trough plate via the tension adjustment support, and an oil-resistant and anti-static conveyor belt surrounding and closely attached to the outer surfaces of the active rubber-coated drive roller and the passive following roller. A concave positioning soft support for placing new energy vehicle parts is provided on the top surface of the oil-resistant and anti-static conveyor belt; a self-lubricating support slide plate is installed on the inner bottom surface of the horizontal U-shaped conveyor trough and located below the oil-resistant and anti-static conveyor belt; a limiting guide side plate is fixed to the inner walls of both sides of the horizontal U-shaped conveyor trough; and a transparent dustproof observation cover is installed on the top of the limiting guide side plate. Heavy-duty shock-absorbing casters are installed under the bottom load-bearing base frame; horizontal stable support studs are installed at the four corners of the bottom load-bearing base frame; and a circular pressure-bearing base is fixed at the bottom of the horizontal stable support studs. An external controller mounting bracket installed on the side of the horizontal U-shaped conveyor trough, a logic controller housing fixed on the external controller mounting bracket, a speed adjustment knob set on the panel of the logic controller housing, and a frequency converter drive module installed inside the logic controller housing; An inclined guide slide plate installed at the feed inlet of the horizontal U-shaped conveyor trough, a sponge anti-collision layer set on the surface of the inclined guide slide plate, an arc-shaped discharge hopper installed at the discharge outlet of the horizontal U-shaped conveyor trough, and a soft damping brush set on the inner side of the arc-shaped discharge hopper. The material sensing support column is installed on the horizontal U-shaped conveying trough plate, the infrared material detection head is fixed at the top of the material sensing support column, the cable collection winding frame is set in the middle of the vertical height support frame, the metal heat dissipation mesh cover for protecting the direct-connected geared motor, the operation status indicator light is installed on the side edge of the horizontal U-shaped conveying trough plate, and the signal shielded control line connecting the infrared material detection head and the logic controller housing.

[0006] Furthermore, the bottom load-bearing base frame is made of rectangular steel pipes welded into a lattice frame, and the vertical height support frame is fixed on the bottom load-bearing base frame by a connecting plate with sliding holes. By changing the fastening position of the connecting plate in the sliding holes, the height adjustment of the horizontal U-shaped conveying trough plate relative to the ground can be realized.

[0007] Furthermore, the shaft core of the active rubber-coated drive roller is made of 45# quenched and tempered steel, and the outer circumferential surface of the active rubber-coated drive roller is hot-vulcanized with a layer of nitrile rubber with a thickness of 8mm-12mm. The surface of the rubber layer is engraved with cross-mesh herringbone drainage and chip removal grooves to improve the grip of the oil-resistant and anti-static conveyor belt in an oily environment.

[0008] Furthermore, the output shaft of the direct-drive geared motor is directly connected to one end of the active rubber-coated drive roller via a tension coupling. The direct-drive geared motor has a built-in electromagnetic brake so that when the system loses power or triggers an emergency stop, the oil-resistant and anti-static conveyor belt can be stopped instantly by mechanical friction.

[0009] Furthermore, the tension adjustment support includes a horizontal guide rail and a sliding bearing seat disposed on the horizontal guide rail. The front end of the sliding bearing seat contacts an adjustment screw. By rotating the adjustment screw, the sliding bearing seat is pushed to make linear reciprocating motion on the horizontal guide rail, thereby changing the center distance between the passive following roller and the active rubber coating drive roller.

[0010] Furthermore, the concave positioning soft support is made of thermoplastic polyurethane elastomer, and its shape matches the motor housing or battery pack frame of the new energy vehicle. The concave positioning soft support is detachably fixed to the bearing surface of the oil-resistant and anti-static conveyor belt by stainless steel countersunk screws.

[0011] Furthermore, the self-lubricating support slide plate is made of polytetrafluoroethylene composite material, and its width is greater than that of the oil-resistant and anti-static conveyor belt. The edge of the self-lubricating support slide plate is provided with an upwardly inclined arc guide surface to prevent the edge of the oil-resistant and anti-static conveyor belt from curling during operation.

[0012] Furthermore, the transparent dustproof observation cover is movably connected to the limiting guide side plate via a hinge. The transparent dustproof observation cover is made of high-strength tempered glass or polycarbonate sheet, allowing operators to observe the conveying posture of internal components without opening the cover.

[0013] Furthermore, the bottom of the arc-shaped hopper is inclined at a downward angle of 20 to 35 degrees to the horizontal plane, and the soft damping brush is made of nylon fiber, which can generate flexible friction resistance to the sliding parts, thereby reducing the sliding speed of the parts and preventing collision damage to the parts.

[0014] Furthermore, the variable frequency drive module and the infrared material detection head form a closed-loop feedback. When the infrared material detection head does not detect the passing of a component within a preset time, the variable frequency drive module controls the direct-drive geared motor to enter a low-power standby mode.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. To improve the surface quality protection of precision parts, this invention constructs a flexible contact mechanism throughout the entire process by setting a sponge anti-collision layer at the inlet and a soft damping brush at the outlet. The sponge layer absorbs the impact energy of the incoming material, while the brush achieves uniform and smooth sliding of the parts through physical damping, effectively eliminating common surface bumps, scratches, and deformations of new energy parts, and reducing the defect rate.

[0016] 2. Achieving ultimate transmission efficiency and simplified maintenance, this solution completely eliminates the easily worn, high-noise, and lubrication-required transmission chain, adopting a direct-drive geared motor to drive the active rubber-coated drive roller. This direct-drive structure has higher mechanical efficiency, and by eliminating the need for lubrication, it ensures a clean production environment. Simultaneously, in conjunction with a metal heat dissipation mesh, it significantly extends the service life of the power system and reduces subsequent maintenance costs.

[0017] 3. Excellent load stability and energy-saving characteristics: By laying self-lubricating support slides under the conveyor belt, and utilizing the extremely low coefficient of friction of ultra-high molecular weight polyethylene, back-to-back low-resistance sliding is achieved. This not only supports heavy components and prevents belt collapse, but also significantly reduces starting torque and operating power consumption. Combined with frequency conversion control logic, it achieves excellent energy-saving effects.

[0018] 4. Excellent electrical reliability and electromagnetic compatibility: Addressing the complex electromagnetic environment of new energy workshops, this invention employs a signal-shielded control line connected to the infrared material detection head. The shielding layer effectively blocks external high-frequency noise signals, ensuring the accuracy of material counting and the stability of the automated logic. Simultaneously, the cable collection and winding rack eliminates the safety hazards of messy cables in industrial settings.

[0019] 5. Highly interactive and transparent operation: The combination of a transparent dustproof observation cover and operational status indicator lights allows operators to clearly understand the movement and position of components and the health status of the equipment without stopping the machine. This visual management approach greatly improves the flexibility of on-site production scheduling and the speed of emergency response. Attached Figure Description

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0029] Please see Figures 1 to 8 This invention provides a conveyor belt for the production of new energy vehicle components.

[0030] First, the bottom load-bearing base frame 1 serves as the physical reference for the entire equipment, and it is welded from Q235B medium carbon steel square tubing. Compared to traditional channel steel, this structure has better torsional stiffness, ensuring that the base does not undergo significant deformation when bearing components weighing over 200kg. Heavy-duty shock-absorbing casters 14 at the four corners of the base provide flexible movement. To eliminate the influence of wheel elasticity on conveying accuracy after the equipment is positioned, rotating horizontally stable support studs 15 ensure that the circular pressure-bearing base 16 is in close contact with the ground, transferring the entire weight of the machine from the wheels to the rigid studs.

[0031] In the vertical dimension, the vertical support frame 2 adopts a modular hole design. The ingenuity of this design lies in the fact that when the upstream and downstream docking heights of the new energy vehicle production line change, such as when transferring from the die-casting section to the testing section, the operator only needs to loosen the bolts to adjust the height of the horizontal U-shaped conveyor trough 3 within a range of 300mm.

[0032] This solution abandons the traditional transmission chain structure and adopts a high-efficiency and simple direct drive solution.

[0033] The active rubber-coated drive roller 5 is installed at the front end, and its shaft core is heat-treated to enhance fatigue strength. Its surface, with a heat-cured nitrile rubber layer, not only has excellent oil resistance, preventing cutting fluid corrosion, but its herringbone grooves also allow for rapid oil drainage in humid environments, ensuring frictional grip with the oil-resistant and anti-static conveyor belt 9. The drive source is a direct-drive geared motor 6, which is directly locked to the end of the drive roller shaft via a rotating bearing positioning seat 4, eliminating the vibration and lubrication requirements associated with chain drives.

[0034] To address the heat generated by the motor during high-frequency start-stop operations, this embodiment includes a metal heat dissipation mesh cover 28 around the motor. This mesh cover not only prevents work gloves from being caught in the motor fan, but its porous aluminum alloy material also increases the heat dissipation area. Combined with the motor's built-in forced air cooling, this allows the motor to operate stably and continuously in a production workshop with an ambient temperature of 40°C, keeping the temperature rise below 65K.

[0035] At the end of the conveyor belt, the tension adjustment support 7 is driven by a lead screw and nut pair to passively follow the rotating roller 8. This design allows maintenance personnel to fine-tune the belt tension using only a wrench, greatly reducing downtime for maintenance.

[0036] In view of the special characteristics of new energy vehicle parts, this embodiment has designed a sophisticated buffer mechanism at the inlet and outlet ends.

[0037] As the part slides in via the inclined guide slide plate 21, the sponge anti-collision layer 22 acts as the first flexible barrier, converting the part's gravitational potential energy into the sponge's deformation energy. Subsequently, the part falls into the concave positioning soft support 10 on the oil-resistant and anti-static conveyor belt 9. The radius of curvature of this positioning support is designed based on the characteristics of the motor housing, effectively limiting the inertial displacement of the part during high-speed start-up and shutdown.

[0038] Beneath the conveyor belt, a self-lubricating support slide plate 11 is laid on the inner bottom surface of the U-shaped trough. This slide plate is made of ultra-high molecular weight polyethylene, which has an extremely low coefficient of friction. This dry lubrication characteristic results in almost no power loss between the conveyor belt bottom surface and the slide plate, and avoids pollution of the conveying environment by lubricating oil. Meanwhile, the limiting guide side plate 12 and the transparent dustproof observation cover 13 together form a relatively enclosed conveying space, preventing workshop dust from falling onto precision parts, and allowing quality inspectors to easily observe the operating status in real time through the transparent PC material.

[0039] At the discharge end, the soft damping brush 24 installed on the inner side of the arc-shaped hopper 23 plays a crucial deceleration role. The nylon brush reduces the sliding speed of the parts to below 0.2m / s through dense friction with the outer wall of the parts, ensuring that they are handled gently when falling into the subsequent turnover box.

[0040] An infrared material detection head 26, mounted on a material sensing support 25, scans the space above the conveyor belt in real time on the side of the U-shaped trough. When the detection head senses a part passing by, the signal is transmitted to the logic controller housing 18 on the external controller mounting bracket 17 via the signal shielded control line 30.

[0041] In new energy production workshops, electromagnetic interference may occur from high-frequency welding equipment or large frequency converters. Traditional control lines are prone to false triggering. The signal shielded control line 30 selected in this embodiment has a high-density tinned copper wire braided shielding layer, which can effectively block high-frequency pulse interference in the space and ensure that every passing part can be accurately counted.

[0042] After receiving the signal, the variable frequency drive module 20 inside the controller controls the acceleration curve of the motor through the parameters set by the speed adjustment knob 19. If the detection head does not sense any material within the set time, the system will automatically control the motor to enter a very low speed cruise state or a sleep state, achieving an energy saving rate of over 35%.

[0043] All control and power cables are neatly stored on the cable collection winding rack 27 in the middle of the support frame. This winding rack is designed with anti-detachment clips, so the cables will not shake or wear even when the equipment is moved. The operation status indicator light 29 serves as a human-machine interface, flashing at different frequencies to inform the operator whether the system is in energy-saving standby, normal operation, or overload alarm mode.

[0044] This invention relates to a conveyor belt for manufacturing new energy vehicle components. Its complete working process encompasses four stages: material introduction, flexible conveying, intelligent detection, and controlled discharge, which are detailed below: Phase 1: Orderly Material Introduction When new energy vehicle components are transferred from the upstream station to this equipment, the components first come into contact with the inclined guide slide plate 21. At this time, the impact on the surface of the component is absorbed by the sponge anti-collision layer 22. Under the action of gravity, the component smoothly enters the area covered by the horizontal U-shaped conveyor trough plate 3. Because the surface of the oil-resistant and anti-static conveyor belt 9 is equipped with concave positioning soft supports 10, the component will be accurately embedded in the support, which solves the stability problem of round components easily rolling left and right or sliding back and forth due to inertia on a flat belt.

[0045] Phase Two: Efficient and Stable Transportation The operator sets the production line cycle time using the speed adjustment knob 19. The direct-drive geared motor 6 outputs torque to drive the active rubber-coated drive roller 5 to rotate. The rubber layer on the surface of the drive roller rubs tightly against the oil-resistant and anti-static conveyor belt 9, causing the belt to move along the axis. Throughout the entire length of the conveyor belt carrying the parts, its bottom surface remains in close contact with the self-lubricating support slide plate 11. Due to the self-lubricating properties of the slide plate material, this back-to-back sliding friction minimizes frictional resistance. At this time, the motor fan inside the metal heat dissipation mesh cover 28 rotates at high speed, carrying away the heat generated by the motor. The limiting guide side plates 12 on both sides of the belt, through anti-scratch rubber pads or precise clearance fit, ensure that the belt does not deviate to the left or right under heavy load, and the parts are cleanly and efficiently moved to the end under the protection of the transparent dustproof observation cover 13.

[0046] Phase 3: Intelligent Logic Monitoring When the part moves to the position of the material sensing support 25, its volume blocks the infrared beam emitted by the infrared material detection head 26. The sensing head instantly generates a level change, and this weak signal is transmitted to the central processing unit inside the logic controller housing 18 through the signal shielded control line 30 with strong anti-interference capability.

[0047] The counting logic controls the system to record a valid pulse and update the production count.

[0048] The energy-saving logic states that if the sensor continuously detects material, it indicates that the material flow is dense and the motor is running at full load; if the sensor does not receive a signal for a long time, the frequency converter drive module 20 reduces the output current frequency to slow down the motor.

[0049] Safety feedback: If the operation status indicator light 29 is solid green, it means the process is going smoothly; if a part gets stuck in the sensing area and causes the obstruction time to be too long, the system will automatically trigger the overload protection, and the indicator light will turn red and flash to remind you to maintain.

[0050] Phase 4: Controlled slow discharge The material travels along the conveyor belt to the top of the arc of the passive following roller 8. As the belt flips downwards, the part loses support and enters the arc-shaped discharge hopper 23. Due to gravity, the part has an initial downward velocity, at which point it comes into contact with the soft damping brush 24. The thousands of nylon fibers of the brush generate uniform, dispersed resistance on the outer shell of the part, slowly offsetting the kinetic energy of the part, so that it eventually slides smoothly out of the discharge port at a very low speed and enters the subsequent assembly basket.

[0051] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
