Description

Technical Field

[0001] The present invention relates to a feeding device, and more particularly to a feeding device and a feeding method for automobile part processing. Background Art

[0002] In the process of automobile part processing, the feeding link is the core initial node connecting the parts storage area and the processing station. The precision processing of automobile parts often goes through multiple complex processes such as cutting, drilling, milling, and grinding. Each process places strict requirements on the supply timeliness and stability of the parts. In this context, the core function of the feeding device is to build an efficient transmission link from the storage area to the processing equipment; through precise mechanical transmission and intelligent control, a batch of stored parts are conveyed to the designated processing station at a constant rhythm and stable posture, forming an automated closed-loop of "storage buffer - orderly sorting - precise feeding", so as to avoid the problem of machine idle caused by manual feeding delay or interruption; data shows that in an automated processing scenario, equipment downtime caused by material shortage can result in production capacity losses of thousands of yuan per hour, and a stable feeding system can increase the overall equipment utilization rate to more than 95%; In the existing technology system, most small and medium-sized automobile part processing enterprises still rely on the traditional manual feeding mode. The specific operation process is highly labor-intensive: operators first need to shuttle between the storage area and the production line, and use tools such as handcarts and forklifts to transport the parts to be processed to the temporary storage table beside the production line. The single handling time can vary from 2 to 10 minutes depending on the weight and distance of the parts; after the previous part is processed, the operator needs to immediately pick up the part from the storage table and place it at the processing center. Since the processing equipment usually runs continuously in a minute-level cycle, the operator needs to stay beside the equipment throughout the process, repeating the cycle of handling, waiting, and picking up parts, forming a high-intensity man-machine collaborative operation mode; operators need to maintain high-frequency movements within an 8-12-hour work shift, and the probability of occupational health risks caused by repetitive strain in parts such as the shoulders and waist is more than 40% higher than that of automated positions; And as the operation time goes by, problems such as distraction of attention and slow movement caused by physical exhaustion gradually appear, which further reduces the feeding efficiency by 20%-30% compared with the initial stage of the shift; in addition, the mode that relies entirely on manual labor makes the production line strongly dependent on the skill proficiency and physical condition of the operators, and it is difficult to meet the modern manufacturing requirements of 24-hour continuous production or rapid switching of multiple varieties.

[0014] A feeding method for a feeding device in automotive part processing. The frame is composed of two symmetrical frame seats and is connected into a transmission system through transmission rollers and chains; the drive motor is installed outside any one of the frame seats to drive the transmission rollers to rotate and drive the chain to move in a cycle; the positioning and transfer component is detachably connected to the chain by bolts and moves synchronously with the chain; the positioning and transfer component consists of two positioning columns. The positioning columns are provided with weight-reducing holes to reduce weight and are connected to the chain on both sides; a support plate is arranged inside the positioning columns, and limiters are installed on the outside and the support plate to fix the position of the automotive parts; an arc-shaped guiding surface is arranged on the inner side of the upper half of the positioning column, which can guide the parts lowered by the stacking mechanism to accurately fall above the support plate to avoid deviation. The positioning frame is fixed to the upper end of the frame seat by four columns. The two side columns are connected by a reinforcing plate, and the front and rear ends are reinforced by end plates and diagonal braces; guide columns are detachably installed inside the columns. The pulleys in their installation grooves are in contact with the outer walls of the overlapping automotive parts, reducing the resistance when the parts are lowered through rolling friction and restricting the lateral movement of the parts at the same time to ensure vertical feeding; the photoelectric sensor group (including opposed photoelectric switches and distance sensors) at the top of the positioning frame monitors the remaining quantity and stacking height of the automotive parts in the stacking mechanism in real time. When the material level is lower than the set threshold, the sensor automatically sends a signal to the PLC control system to trigger a replenishment alarm or link the manipulator to start an automatic replenishment process. The first material discharge component includes a support table, the inner arc-shaped support surface of which supports the upper component, and the outer side is slidably connected to the end plate through a guide rod and a limit block; the support cylinder drives the support table to move up and down: when it is necessary to discharge the material, the support cylinder contracts, the support table descends, and the bottom layer of components is released; then the support table is reset and continues to support the upper component; the structure of the second material discharge component is similar to the first material discharge component, and is located below it, cooperating to realize layered material discharge; the first material receiving component and the second material receiving component both include a displacement plate, which is driven up and down by the piston rod in the driving unit; the material receiving cylinder on the displacement plate can push the positioning block and the cross bar, driving the material receiving rod to clamp or release the component; when the stacking mechanism lowers the component, the material receiving rod rises to receive the component, and then moves with the chain to the top of the transmission mechanism, releasing the component to the support plate of the positioning and transfer component; the automobile parts are stacked in the positioning frame, supported layer by layer by the first material discharge component and the second material discharge component, and the pulley provides guidance and limitation; when it is necessary to discharge the material, the support cylinder drives the first material discharge component and the second material discharge component to move upward and downward; The unloading assembly descends to release the bottom-layer components; the drive unit of the receiving assembly drives the displacement plate to rise, and the receiving rod clamps the falling components through the receiving cylinder; the receiving assembly moves with the chain to the top of the transmission mechanism, the receiving cylinder is released, and the components fall onto the supporting plate of the positioning and transfer assembly and are fixed by the limiter; the visual inspection module (industrial camera + image algorithm) at the end of the transmission mechanism performs real-time detection of the posture and position of the automotive components on the positioning and transfer assembly. If the component is detected to be offset or tilted, the PLC control system immediately adjusts the transmission speed or triggers the mechanical correction device (such as pneumatic pusher block) to correct the posture to ensure that the component enters the subsequent processing station with a precise posture; the entire process is coordinated by the integrated PLC control system to coordinate the action sequence of actuators such as the drive motor, support cylinder, drive unit, and receiving cylinder. The operator sets the production parameters such as the transmission speed and unloading speed through the human-machine interface (HMI). The system displays the equipment operation status and fault alarm information in real time to achieve full-process automated monitoring and management; The transmission mechanism transports the parts to the subsequent processing station through chain transmission, completing the loading process.

[0015] The present invention has the following beneficial effects: 1. Traditional manual loading requires operators to frequently carry parts back and forth, and a single handling takes 2-10 minutes, and the efficiency fluctuates due to physical limitations (the efficiency decreases by 20%-30% in the later stage of the shift); this device drives the chain to circulate through the drive motor, and cooperates with the positioning and transfer components and the stacking mechanism to achieve the automation of the entire process of "storage-sorting-transmission", which can continuously and stably supply materials, avoid idling of machine tools due to manual delays, and the comprehensive utilization rate of equipment can be increased to more than 95%; 2. The first unloading assembly and the second unloading assembly in the stacking mechanism drive the support platform to move up and down through the support cylinder, and can release the stacked automobile parts layer by layer (such as releasing parts of different layers alternately) to avoid the chaos caused by the simultaneous falling of multiple layers of parts; the first receiving assembly and the second receiving assembly drive the displacement plate to rise through the driving unit (such as a cylinder), and cooperate with the receiving cylinder to drive the receiving rod to clamp the parts, so as to achieve accurate acceptance of the falling parts and avoid the time loss of manual picking up; 3. A support plate and a limiter are arranged on the inner side of the positioning column of the positioning transfer component, which are detachably connected by screws. The limiter position can be flexibly adjusted according to the size of the component to ensure that the position of the component is fixed during the transmission process; the arc-shaped guide surface guides the components lowered by the stacking mechanism to fall accurately into the support plate to avoid deviation; the guide column and the pulley in the positioning frame fit the outer wall of the component through rolling friction, which not only reduces the resistance to lowering, but also limits the lateral movement of the component, ensuring vertical unloading and avoiding processing errors caused by component posture deviation; 4. The positioning transfer component is detachably connected to the chain, and the guide column and the column are detachably installed, which is convenient for quickly replacing the positioning component or adjusting the guide spacing according to different specifications of automobile parts, adapting to the production needs of multiple varieties and reducing the changeover time; 5. Reduce manual intervention and repetitive labor. Traditional manual loading requires operators to stay beside the equipment throughout the process, repeatedly moving and picking up parts. High-frequency operations within an 8-12 hour shift can easily lead to repetitive strain injuries in the shoulders, waist and other parts (the risk is more than 40% higher than that of automated positions). This device uses automated transmission and positioning, and operators only need to regularly replenish stacked parts, greatly reducing physical exertion and work intensity. 6. Improve production safety. The automated operation mode avoids direct manual contact with high-speed processing equipment, reduces the risk of safety accidents caused by operational errors, and reduces collision damage during component handling, ensuring component quality and operator safety; 7. The frame is connected to the chain by a symmetrical frame seat through transmission rollers, and the structure is compact and stable; the stacking mechanism is located above the transmission mechanism, which occupies a small space and can be adapted to small and medium-sized automotive parts processing production lines, especially suitable for scenes with limited workshop space.

The set parameters include the transmission speed and the discharging speed, and the operating status and fault alarm information of the equipment are displayed in real time.

[0045] A feeding method for a feeding device used in the processing of automotive parts. The frame is composed of two symmetrical frame seats 6 and is connected into a transmission system through transmission rollers 7 and a chain 8; the drive motor 9 is installed on the outer side of any one of the frame seats to drive the transmission rollers to rotate and drive the chain to move in a cycle; providing power for the entire device. The positioning and transfer assembly 5 is detachably connected to the chain 8 by bolts and moves synchronously with the chain 8; responsible for receiving and transferring automotive parts. The positioning and transfer assembly 5 is composed of two positioning columns 10. The positioning columns 10 are provided with weight reduction holes 11 to reduce the weight, and are connected to the chain 8 on both sides; a support plate 12 is arranged on the inner side of the positioning columns, and limit members 13 (detachable by screws) are installed on the outer side and on the support plate to fix the positions of the automotive parts; an arc-shaped guiding surface 15 is arranged on the inner side of the upper half of the positioning column 10, which can guide the parts released by the stacking mechanism to accurately fall above the support plate 12 to avoid offset; The positioning frame 16 is fixed to the upper end of the machine frame seat by four columns 21. The two side columns are connected by a reinforcing plate 22, and the front and rear ends are reinforced by end plates 28 and diagonal braces 29. Guide columns 23 are detachably installed inside the columns 21. The pulleys 27 in their installation grooves are in contact with the outer walls of the overlapping automotive components, reducing the resistance when the components are lowered through rolling friction, and at the same time restricting the lateral movement of the components to ensure vertical feeding. The photoelectric sensor group (including through-beam photoelectric switches and distance sensors) at the top of the positioning frame 16 monitors the remaining quantity and stacking height of the automotive components in the stacking mechanism in real time. When the material level is lower than the set threshold, the sensor automatically sends a signal to the PLC control system to trigger a replenishment alarm or link the manipulator to start the automatic replenishment process; The first material discharging component 17 includes a support table 30. The arc-shaped support surface 31 inside it holds the upper-layer component, and the outside is slidably connected to the end plate through a guide rod 32 and a limit block 33. The support cylinder 35 drives the support table to move up and down: when discharging is required, the support cylinder 35 contracts, the support table 30 descends, and the bottommost component is released; then the support table resets and continues to hold the upper-layer component. The structure of the second material discharging component 18 is similar to that of the first material discharging component 17 and is located below it to cooperate to achieve layered discharging. Both the first material receiving component 19 and the second material receiving component 20 include a displacement plate 36, which is driven to move up and down by the piston rod 38 of a driving unit (such as a cylinder, installed in a driving box 37). The material receiving cylinder 39 on the displacement plate can push the positioning block 50 and the cross bar 51 to drive the material receiving rod 52 to clamp or release the component; when the stacking mechanism lowers the component, the material receiving rod rises to receive the component, and then moves to above the conveying mechanism along with the chain, and releases the component onto the supporting plate of the positioning and transferring component. The automotive components are stacked in the positioning frame 16 and are supported layer by layer by the first material discharging component 17 and the second material discharging component 18, and the pulleys 27 provide guidance and limitation. When discharging is required, the support cylinder 35 drives the first material discharging component and the second material discharging component to descend, and the bottommost component is released; the piston rod 38 of the driving unit of the material receiving component drives the displacement plate 36 to rise, and the material receiving rod 52 clamps the falling component through the material receiving cylinder 39; the material receiving component moves to above the conveying mechanism along with the chain 8, the material receiving cylinder is loosened, and the component falls onto the supporting plate 12 of the positioning and transferring component 5 and is fixed by the limiting member 13. The vision detection module (industrial camera + image algorithm) at the end of the conveying mechanism 2 detects the posture and position of the automotive components on the positioning and transferring component 5 in real time. If it detects that the component is offset or tilted, the PLC control system immediately adjusts the conveying speed or triggers a mechanical correction device (such as a pneumatic pusher block) to correct the posture to ensure that the component enters the subsequent processing station with a precise posture. The entire process is coordinated by the integrated PLC control system to unify the action timing of the driving motor 9, the support cylinder 35, the driving unit, the material receiving cylinder 39 and other actuators. The operator sets production parameters such as the conveying speed and the discharging speed through the human-machine interface (HMI), and the system displays the equipment operation status and fault alarm information in real time to achieve full-process automated monitoring and management; The transmission mechanism conveys the components to the subsequent processing stations through chain drive to complete the loading process; finally, a manipulator is used to clamp them at the subsequent machining centers for processing.

[0046] In the present invention, the stacking mechanism 3 can be replenished by an operator or by a manipulator, which can be specifically selected according to actual needs. If a manipulator is selected for replenishment, an automated loading system can be realized to reduce the number of operators. Especially in the scenario of 24-hour continuous production, there is no need for shift manual feeding, significantly reducing labor costs. Data shows that equipment downtime caused by material shortage can cause losses of thousands of yuan per hour. This device can effectively avoid such losses through stable feeding; in addition, the stable feeding rhythm reduces the mechanical wear of the processing equipment caused by idling or sudden stop, prolongs the service life of the machine tool and transmission components, and reduces maintenance costs. In summary, through automated, precise, and modular design, the present invention effectively solves the problems of low efficiency, high labor intensity, and poor adaptability of traditional manual feeding, and is applicable to the high-efficiency production requirements in the field of automotive parts processing, with significant technological progress and practical value.

[0047] During specific use, a protective fence can be installed outside the frame 1 according to the actual area or needs, and infrared light curtain sensors are set in the dangerous areas of the stacking mechanism 3 and the transmission mechanism 2. When an operator enters the dangerous area by mistake, the light curtain triggers the equipment to stop urgently, and a sound and light alarm is used for prompting.

[0048] Vibration sensors and temperature sensors are installed on key actuators such as the drive motor 9 and the support cylinder (35) to monitor the running state of the equipment in real time. If abnormal vibration or temperature overrun is detected, the system automatically stops and generates a fault code, and the specific fault location (such as "motor overload" "cylinder air leakage") is displayed through the HMI, facilitating quick repair.
