Description

Technical Field

[0001] The present invention relates to the technical field of loading devices, and particularly to a component loading device and a loading method for new energy vehicle body processing. Background Art

[0002] During the processing of new energy vehicle bodies, components need to be transported to the production line via a conveying device and finally the vehicle body is assembled. However, since most components are heavy, manual handling is cumbersome, and a loading device matching the conveying device is often required to transport the components onto the conveying device;

[0003] During the assembly of new energy vehicle bodies, some of the vehicle body components are cylindrical components with uncertain dimensions. To avoid the position offset of the cylindrical components during transportation, these cylindrical components need to be matched with positioning devices of different dimensions during the loading process. The vehicle body structure is complex and the internal space is limited. During the assembly process, cylindrical components of different dimensions need to be reasonably placed at specific positions of the vehicle body, and the vehicle data of different vehicle models are different, resulting in changes in the dimensions of the cylindrical components. In the above situations, the manufacturer needs to redesign the positioning device of the cylindrical component loading device according to the vehicle data to ensure that the cylindrical components can be transported to the set position according to the production line settings and the vehicle body is assembled. The above operations require the manufacturer to purchase fixing devices adapted to different dimensions, increasing the loading cost;

[0004] For this reason, we propose a component loading device and a loading method for new energy vehicle body processing to solve the above problems. Summary of the Invention

[0030] Advantageous effects

[0031] Compared with the prior art, the present invention provides a parts feeding device and a feeding method for new energy vehicle body processing, having the following advantageous effects:

[0032] Through the setting of Y-shaped support blocks with adjustable spacing, it is possible to adapt to the feeding of cylindrical parts of different lengths. This kind of Y-shaped support block with adjustable spacing can greatly improve the adaptability of the feeding equipment to cylindrical parts of different specifications, eliminating the need to specially design and manufacture a set of feeding devices for each size of parts, thereby reducing the equipment replacement time and cost. Moreover, the Y-shaped support blocks can be precisely adjusted according to the length of the cylindrical parts. These Y-shaped support blocks can provide stable support for the parts in the horizontal and vertical directions, and by adjusting the spacing, the parts can always be kept in the appropriate position during the feeding process, avoiding processing errors caused by workpiece position deviation.

[0033] Through the setting of the gear and the gear ring, when rotating one of the bidirectional threaded rods, multiple bidirectional threaded rods can be rotated simultaneously. Only by controlling the movement of one bidirectional threaded rod, the coordinated movement of multiple threaded rods can be achieved. By only controlling one input shaft, the coordinated movement of the entire material handling system can be realized, reducing the control difficulty.

[0034] Through the deployable setting of the arc-shaped slider, it can adapt to the fixation of parts of different sizes, and the arc-shaped slider and the Y-shaped support block can better fit the surface of the parts, increasing the versatility of the equipment. At the same time, the setting of the arc-shaped slider can prevent small-sized parts from detaching from the surface of the feeding device during the conveying process, avoiding the situation of part position deviation, and the arc-shaped slider can better fit the surface of the parts, effectively reducing damage to the part surface compared with the traditional fixation method.

[0035] Through the setting of the recycling transfer track, when the feeding conveyor belt is mechanically damaged and cannot be accurately docked with the Y-shaped support block, the parts in this part will be recycled via the recycling transfer track and re-fed, thus preventing too many parts from accumulating at the top of the feeding conveyor belt and affecting the parts feeding process. By diverting the damaged parts through the recycling transfer track and re-feeding them, the obstacles at the top of the conveyor belt can be quickly cleared, enabling the feeding conveyor belt to continue to work normally, reducing production interruptions caused by conveyor belt blockage, and thus improving the feeding efficiency.

[0036] Through the setting of the arc track in the recovery transmission track, the sliding speed of the parts falling through the inclined track in the recovery transmission track will be buffered within the arc track, and with the cooperation of the round rod, the parts will stay within the arc track, thus avoiding the situation where the sliding speed of the parts is too fast and the excessive impact force causes damage to the parts;

[0037] Through the setting of the reciprocating toggle rod and the round rod, in cooperation with the recovery transmission track, the parts recovered on the recovery transmission track can be conveyed. After collection, they can be used for reloading. The reciprocating toggle rod can control the number of parts sliding down at one time, thus avoiding the situation where a large number of parts slide down simultaneously and impact each other, causing damage to the parts. In addition, the cooperation between the toggle rod and the round rod can prevent the parts from getting stuck in the arc track of the recovery transmission track, thus ensuring the smooth progress of the parts recovery work.

[0074] Embodiment 2

[0075] A method for loading parts for new energy vehicle body processing includes the following steps:

[0076] Step 1: Parts handling:

[0077] According to the production plan and product BOM (Bill of Materials), determine the types and quantities of automotive parts required, find the automotive parts that need to be loaded in the warehouse, move the parts to the production line using forklifts and other handling tools, and batch and sort the parts according to the production sequence and assembly sequence;

[0078] Step 2: Equipment debugging:

[0079] Adjust the distance between the two Y-shaped support blocks 29 within the same moving track limiting block 28 according to the component size data. Then, start the micro-motor 24 through the controller, adjust the rotation speed of the micro-motor 24 and the conveying speed of the feeding conveyor belt 42, and ensure that the discharge port of the feeding conveyor belt 42 is aligned with the top of the Y-shaped support block 29. The discharge port of the roller conveying device 12 is accurately docked with the input end of the production line to ensure that the components can accurately enter the production process;

[0080] Step 3: Place the components:

[0081] Place the transported automotive components on the feeding conveyor belt 42, convey them to the Y-shaped support block 29 via the feeding conveyor belt 42, and convey them into the production line via the Y-shaped support block 29 and the roller conveying device 12;

[0082] Step 4: Assemble the components:

[0083] Accurately place the components conveyed by the feeding equipment in the correct position on the production line, and the workers manually assemble the components.

[0084] The working process and principle of the overall content of the above embodiments are as follows:

[0085] Preparation work:

[0086] The staff determines the size of the components to be conveyed. Both ends of the bidirectional threaded rod 27 are fixedly connected with knobs. Then, turn the knobs according to the component size. As the knobs rotate, the bidirectional threaded rod 27 will rotate accordingly. Since the two ends of the bidirectional threaded rod 27 are provided with threads in opposite directions, the Y-shaped support blocks 29 threadedly connected to both ends of the bidirectional threaded rod 27 will move in a direction of approaching or separating from each other as the bidirectional threaded rod 27 rotates. The specific movement direction refers to the initial position of the Y-shaped support block 29 and the size of the components to be conveyed, so that the distance between the two Y-shaped support blocks 29 is slightly smaller than the length of the components to be conveyed. During the above process, the movement of the Y-shaped support block 29 is restricted by the moving track limiting block 28 and can only perform horizontal displacement;

[0087] And because gears 2071 are fixedly connected to both ends of each bidirectional threaded rod 27, a gear ring 26 is rotatably connected to the outer surface of the driven turntable 25, and the gear ring 26 meshes with the gears 2071. Therefore, as one of the bidirectional threaded rods 27 rotates, the other threaded rods will rotate under the meshing action of the gears 2071 and the gear ring 26, so that the Y-shaped support blocks 29 on each bidirectional threaded rod 27 can move synchronously. Rotating only one bidirectional threaded rod 27 can drive the other bidirectional threaded rods 27 to rotate simultaneously, thereby adjusting the position of the Y-shaped support block 29;

[0088] Through the arrangement of the gear 2071 and the gear ring 26, when one of the bidirectional threaded rods 27 is rotated, multiple bidirectional threaded rods 27 can be rotated simultaneously. Only by controlling the movement of one bidirectional threaded rod 27 can the coordinated movement of multiple threaded rods be achieved. By only controlling one input shaft, the coordinated movement of the entire material handling system can be realized, reducing the control difficulty;

[0089] Through the arrangement of the adjustable-spacing Y-shaped support blocks 29, the feeding of cylindrical parts with different lengths can be adapted. Such adjustable-spacing Y-shaped support blocks 29 can greatly improve the adaptability of the feeding equipment to cylindrical parts of different specifications, eliminating the need to specifically design and manufacture a set of feeding devices for each size of parts, thereby reducing the equipment replacement time and cost. Moreover, the Y-shaped support blocks 29 can be precisely adjusted according to the length of the cylindrical parts. These Y-shaped support blocks 29 can provide stable support for the parts in the horizontal and vertical directions, and by adjusting the spacing, the parts can always be kept in the appropriate position during the feeding process, avoiding processing errors caused by workpiece position deviation;

[0090] Subsequently, the automotive parts to be transported are placed on the feeding conveyor belt 42. Then, the staff starts the feeding conveyor belt 42 through an external controller, and the parts are transported via the feeding conveyor belt 42 for feeding the automotive parts;

[0091] Feeding of parts:

[0092] The feeding conveyor belt 42 transports the parts to one end close to the fixed frame 22. During the transportation of the feeding conveyor belt 42, the staff starts the micro-motor 24 through an external controller. After the micro-motor 24 is started, it rotates at the speed set by the controller. Since the rotating shaft 23 is fixedly connected to the output shaft end of the micro-motor 24, the rotating shaft 23 will rotate inside the fixed frame 22 with the start of the micro-motor 24;

[0093] In the above process, as the rotating shaft 23 rotates, the driven turntables 25 fixedly connected to both ends of the rotating shaft 23 will rotate accordingly. At this time, the Y-shaped support blocks 29 arranged on the driven turntables 25 will rotate together with the driven turntables 25;

[0094] And as the feeding conveyor belt 42 transports the cylindrical parts to be fed from the bottom end to the top end of the feeding conveyor belt 42, the parts transported to the top end of the feeding conveyor belt 42 will contact the Y-shaped support block 29 closest to the feeding conveyor belt 42 (refer to Figure 7 , specifically, the first Y-shaped support block 29 on the right with reference to the vertical center line of the driven turntable 25). At this time, the cylindrical part will contact this Y-shaped support block 29 and be fixed by the Y-shaped support block 29;

[0095] As the rotation drives the driven turntable 25 to rotate to a position close to one end of the roller conveyor 12, the components located within the Y-shaped support block 29 will disengage from the Y-shaped support block 29, enter the surface of the roller conveyor 12, and the components will be conveyed to the production line via the roller conveyor 12;

[0096] During the above process, as the driven turntable 25 rotates, when the size of the component to be conveyed is larger than the inner diameter of the Y-shaped support block 29, the top of the Y-shaped support block 29 will support the bottom of the component. At this time, the bottom of the component will not contact the top surface of the extrusion block 33, and the rotation of the driven turntable 25 drives the Y-shaped support block 29 to batch-convey the components onto the roller conveyor 12;

[0097] When the size of the component to be conveyed is smaller than the inner diameter of the Y-shaped support block 29, after the component enters the interior of the Y-shaped support block 29, when the Y-shaped support block 29 rotates to the vertical state along with the driven turntable 25, the bottom of the component will contact the top end of the extrusion block 33, and the extrusion block 33 will move downward under the gravity of the component. At this time, the driven connecting rods 35 rotatably connected to both sides of the bottom end of the extrusion block 33 will move accordingly. Since the driven connecting rods 35 are rotatably connected to the connecting rod 34, and the connecting rod 34 is composed of two cross bars with an acute angle between them and fixedly connected to each other, during the process that the driven connecting rods 35 gradually move from an inclined state to a horizontal state, the connecting rod 34 will move in a direction away from the extrusion block 33 under the action of the driven connecting rods 35;

[0098] During the movement of the above-mentioned connecting rod 34, it will drive the arc-shaped slider 31 fixedly connected to it to slide within the Y-shaped support block 29. Due to the arc-shaped groove provided on the Y-shaped support block 29, the movement of the arc-shaped slider 31 is restricted by the arc-shaped groove. At this time, the arc-shaped slider 31 will extend out from both ends of the Y-shaped support block 29, semi-enclose the top of the Y-shaped support block 29, and the arc-shaped slider 31 will synchronously compress the connecting spring 32 arranged within the arc-shaped groove during its movement to restrict the smaller-diameter cylindrical components;

[0099] Refer to Figure 7 When the Y-shaped support block 29 continues to move closer to the roller conveyor 12, at this time, the extrusion force exerted on the extrusion block 33 within the Y-shaped support block 29 in the vertical direction by the component gradually decreases. Therefore, under the action of the rebound of the connecting spring 32, the above structure will gradually return to its initial state. In this state, the arc-shaped slider 31 extending out of the Y-shaped support block 29 will re-enter the interior of the Y-shaped support block 29, and under the rotation action of the driven turntable 25, the components within the Y-shaped support block 29 will enter the roller conveyor 12;

[0100] The expandable setting of the arc-shaped slider 31 can adapt to the fixation of parts of different sizes, and the arc-shaped slider 31 and the Y-shaped support block 29 can better fit the surface of the parts, increasing the versatility of the equipment. At the same time, the setting of the arc-shaped slider 31 can prevent the smaller parts from detaching from the surface of the feeding device during the conveying process, causing the position of the parts to shift, and the arc-shaped slider 31 can better fit the surface of the parts, which can effectively reduce the damage to the surface of the parts compared with the traditional fixing method;

[0101] As the feeding conveyor belt 42 continues to convey, the parts placed on the feeding conveyor belt 42 will be piled up at the top of the feeding conveyor belt 42, that is, as the feeding conveyor belt 42 is continuously used, the friction between the parts and the feeding conveyor belt 42 changes, or the feeding conveyor belt 42 is mechanically worn, resulting in a deviation between the feeding speed of the feeding conveyor belt 42 and the initial limited speed. At this time, some of the parts transported to the top of the feeding conveyor belt 42 cannot accurately contact the Y-shaped support block 29;

[0102] In this state, the parts will fall onto the recovery transmission track 43 through the gap between the top of the feeding conveyor belt 42 and the driven turntable 25;

[0103] It should be noted that the recovery and transmission track 43 is formed by connecting a section of an inclined track, a curved track, a horizontal track and another end of an inclined track in sequence, so the parts will fall into the curved track after passing through the inclined track and contact the round rod 55 in the curved track;

[0104] In the above process, since the crank 51 is fixedly connected to the end of the rotating shaft 23 away from the micro motor 24, the rotation of the rotating shaft 23 will cause the crank 51 to rotate around the rotating shaft 23, and the swing rod 52 rotatably connected to the other end of the crank 51 will move synchronously. At this time, the driven rod 53 rotatably connected to the swing rod 52 and slidably connected to the through slot provided in the positioning frame 41 will generate horizontal reciprocating motion in the through slot;

[0105] As the driven rod 53 moves, the toggle rod 54 rotatably connected to the driven rod 53 will move accordingly. Since the toggle rod 54 is composed of two straight rods of different lengths, the two straight rods are at an acute angle, and the toggle rod 54 is rotatably connected to the outer wall of the positioning frame 41 at the corner point, the toggle rod 54 will rotate with the connection point with the positioning frame 41 as the fulcrum, and continue to swing with the reciprocating motion of the driven rod 53;

[0106] Since the round rod 55 provided on the toggle rod 54 is located above the arc track, the movement of the round rod 55 and the toggle rod 54 can contact the components located in the arc track, and the components located in the arc track are moved out of the arc track, so that the components continue to slide along the horizontal track and the inclined track, and the components are collected;

[0107] The components conveyed by the roller conveyor 12 can be docked with the production line, and finally the feeding of the components can be completed.

[0108] Through the setting of the recycling transfer track 43, when the feeding conveyor belt 42 is mechanically damaged and cannot be accurately docked with the Y-shaped support block 29, this part of the components will be recycled through the recycling transfer track 43 and re-fed, so as to avoid excessive accumulation of components at the top of the feeding conveyor belt 42 and affect the process of component feeding. By diverting the damaged components through the recycling transfer track 43 and re-feeding them, the obstacles at the top of the conveyor belt can be quickly cleared, allowing the feeding conveyor belt 42 to continue to work normally, reducing production interruptions caused by conveyor belt blockage, and thus improving the feeding efficiency.

[0109] Through the setting of the inner arc track in the recycling transfer track 43, the sliding speed of the components falling through the inclined track in the recycling transfer track 43 will be buffered in the arc track, and with the cooperation of the round rod 55, they will stay in the arc track, thus avoiding the situation where the components are damaged due to too fast sliding speed and too large impact force.

[0110] Through the setting of the reciprocating toggle rod 54 and the round rod 55, in cooperation with the recycling transfer track 43, the components recycled on the recycling transfer track 43 can be conveyed and collected for re-feeding. The reciprocating toggle rod 54 can control the number of components sliding down at one time, thus avoiding the situation where a large number of components slide down at the same time and impact each other, causing damage to the components. In addition, the cooperation between the toggle rod 54 and the round rod 55 can prevent the components from getting stuck in the arc track of the recycling transfer track 43, thus ensuring the smooth progress of the component recycling work.
