Description

Technical Field

[0001] This invention relates to the field of automotive parts conveying equipment technology, specifically to an automated automotive parts loading and turning equipment and processing technology. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. Common automotive parts include: fuel injectors, suspension, springs, main reducer, subframe, brake pump, chassis, battery, oil cooler, tensioner, transmission, timing belt, wheels, cylinders, carbon canister, inner tube, throttle body, drive shaft, battery, lubricating oil, sensors, cigarette lighter, floor, etc. Automotive parts are an indispensable part of a car.

[0003] The automotive floor is an important component of the lower part of the car body and one of the important factors affecting the quality of the car. The automotive floor is a sheet metal structural component. Currently, during the processing of automotive floor, automated feeding and turning equipment is required to feed and transport the automotive floor to subsequent processing equipment for cutting, grinding, welding and polishing.

[0004] Chinese patent document CN212580820U discloses a high-speed conveying device for the front floor of an automobile, including a frame. The frame has workpiece placement platforms at both its front and rear ends, each platform comprising two spaced-apart support frames. A movable trolley is mounted on the frame, passing between the two support frames of the placement platform. The trolley has a liftable bracket, which, via a lifting mechanism, lifts and places workpieces onto the placement platform. A guide rail is mounted on the frame between the two support frames of the placement platform, and the trolley moves along the guide rail. A rack is also mounted on the frame. The trolley includes a support, a guide block located at the bottom of the support and connected to the guide rail, a drive motor mounted on the support, and a gear connected to the drive motor. The wheel meshes with the rack; the lifting mechanism consists of several lifting cylinders, which are fixed to the support, and the bracket is connected to the lifting cylinder; the bracket is equipped with a pin cylinder; the two support frames of the placement platform and the bracket are each equipped with a detachable positioning pin; there are two guide rails, which are spaced apart, and the rack is located between the two guide rails; the gear is located at the bottom of the support, and the support has a through hole, through which the drive motor is connected to the gear; the bottom of the support at both the front and rear ends in the direction of movement is equipped with a stop block; the front and rear ends of the frame are equipped with a limiting mechanism, which includes a limiting cylinder fixed to the front and rear ends of the frame and a rubber block connected to the piston rod of the limiting cylinder; the rubber block is located on the moving path of the stop block.

[0005] During operation, after the workpiece is processed in the previous process, the robot arm of the previous process picks up the workpiece and places it on a placement table on the machine frame. At this time, the bracket on the trolley is lower than the height of the support frame, meaning that the workpiece only contacts the support frame and not the bracket. After the workpiece is placed on the placement table, the trolley moves to the position of the two support frames corresponding to the placement table. The bracket on the trolley rises through the lifting mechanism, which then lifts the workpiece, causing it to detach from the placement table. Then the trolley begins to move. When the trolley reaches the position of another placement table, the bracket descends through the lifting mechanism, and the workpiece falls onto the other placement table. The bracket detaches from the workpiece, the trolley resets, and the robot arm of the next process picks up the workpiece for the next process.

[0006] In the above-mentioned technology, when it is necessary to process both the upper and lower surfaces of the car floor, after processing one side of the car floor, the car floor is removed from the placement table, flipped over, and then placed back onto the placement table, resulting in low processing efficiency of the car floor. Summary of the Invention

[0007] This invention provides an automated loading and flipping device and processing technology for automotive parts, aiming to solve the technical problem of low processing efficiency of automotive floor when processing both the upper and lower surfaces of the car floor is required. This is caused by processing one side of the car floor, removing it from the loading table, flipping it over, and then placing it back on the loading table.

[0008] In a first aspect, the present invention provides an automated loading and turning device for automotive parts, comprising a frame and a conveying mechanism disposed on the frame for conveying automotive parts. The conveying mechanism includes a first conveyor frame and a second conveyor frame, which respectively form two processing stations with the frame and are used to realize the feeding and unloading of automotive parts. A turning mechanism is disposed on the frame, comprising a sliding block slidably connected to the frame in a horizontal direction and a turning frame rotatably connected to the sliding block. The sliding block is located between the two processing stations. A positioning mechanism is disposed on the frame for limiting the position of the automotive parts on the turning frame. When the positioning mechanism limits the position of the automotive parts on the turning frame, the turning frame is translated, and the turning frame can drive the automotive parts to translate between the two processing stations and turn the turning frame, which can drive the automotive parts to turn on the sliding block, so as to simultaneously realize the turning of automotive parts and the switching of processing stations.

[0009] Beneficial effects: By setting up a flipping mechanism and a positioning mechanism, when processing automotive parts, the automotive parts are first placed on a conveyor frame and enter a processing station. Then, the top surface of the automotive parts is processed by the processing equipment. After processing, the automotive parts are conveyed on the conveyor frame and then to the flipping frame. Next, the positioning mechanism fixes the automotive parts on the flipping frame. Then, by rotating the flipping frame 180 degrees, the flipping frame can drive the automotive parts to flip and rotate 180 degrees. Then, the automotive parts are conveyed to another processing station, where the processing equipment processes the automotive parts. This achieves processing of both the top and bottom surfaces of the automotive parts, which can improve the processing efficiency of automotive parts.

[0010] Preferably, the positioning mechanism includes a longitudinal positioning component, a transverse positioning component, and a clamping component. The longitudinal positioning component includes two support frames slidably connected to the tilting frame along the width direction of the first conveyor frame, a rotating roller rotatably mounted on the support frame, and a conveyor belt wound around the rotating roller. When the two support frames slide towards each other, they can position the automotive parts in the width direction of the first conveyor frame. The conveyor belt is used to carry and transport the automotive parts.

[0011] Beneficial effects: The longitudinal positioning component positions the automotive parts on both sides along the width direction of the conveyor frame, and the transverse positioning component positions the automotive parts on both sides along the length direction of the conveyor frame. This enables the fixed positioning of the automotive parts, and the clamping component clamps the automotive parts on both the top and bottom sides to prevent them from falling off during the flipping process.

[0012] Preferably, the lateral positioning component includes an adjusting frame disposed on the flipping frame, a limiting plate fixed to one end of the adjusting frame, a slider slidably connected to the adjusting frame along the length direction of the conveying frame, and a positioning plate rotatably connected to the slider. When the positioning plate is flipped to a horizontal state, the automotive parts can pass over the positioning plate and be conveyed to the flipping frame. When flipped to a vertical state, the slider drives the positioning plate to cooperate with the limiting plate to position the automotive parts along the length direction of the conveying frame.

[0013] Preferably, the clamping assembly includes a translation frame slidably connected to the carrier frame along the width direction of the first conveyor frame, a clamping frame slidably connected to the translation frame along the vertical direction, and a clamping band disposed on the clamping frame. The clamping band cooperates with the conveyor belt to clamp the automotive parts on both the top and bottom sides to prevent them from falling off during flipping.

[0014] Preferably, a lifting frame is slidably mounted on the adjusting frame in the vertical direction. The lifting frame includes a lifting plate extending horizontally along the length of the conveying frame. A groove is formed on the side wall of the lifting plate facing the positioning plate. A rotating column is fixedly mounted on one side of the positioning plate. The axis of the rotating column is spaced apart from the rotation axis of the positioning plate, and one end of the rotating column extends into the groove and is stopped by the groove wall. When the lifting frame is raised or lowered, the positioning plate can be driven to flip through the rotating column.

[0015] Beneficial effects: It can control the positioning plate to switch between vertical and horizontal states. In the horizontal state, the car parts can pass over the positioning plate and be transported to the flipping frame. When the positioning plate is flipped up to the vertical state, the slider can drive the positioning plate and the limit plate to clamp the car parts, thereby achieving the positioning of the car parts.

[0016] Preferably, a second lead screw is rotatably mounted on the tilting frame, the second lead screw is threadedly connected to the adjusting frame, and the adjusting frame can move along the width direction of the conveying frame under the drive of the second lead screw.

[0017] Beneficial effects: When processing automotive parts, after the flipping frame flips the automotive parts over, the adjusting frame will be above the automotive parts. By controlling the movement of the adjusting frame, it is possible to avoid the adjusting frame obstructing the area of ​​the automotive parts to be processed.

[0018] Preferably, a slide rod is slidably mounted on the adjusting frame in the vertical direction, the lifting plate is fixedly connected to the upper end of the slide rod, and a slide rod driving mechanism for driving the slide rod to rise and fall is installed at the bottom of the adjusting frame.

[0019] Preferably, the support frame is fixedly provided with a horizontally arranged side plate, the translation frame is horizontally slidably fitted with the side plate, a second cylinder is fixedly installed on the side plate, and the telescopic part of the second cylinder is fixedly connected to the translation frame for driving the translation frame to slide.

[0020] Preferably, a first lead screw extending along the width direction of the conveyor frame is rotatably mounted on the tilting frame. The first lead screw is threadedly connected to the support frame and is used to drive the two support frames to slide closer to or further away from each other.

[0021] Beneficial effects: By setting the first lead screw, the two carrier frames can be driven to slide closer or further apart, thereby realizing the positioning, clamping and unlocking of automotive parts along both sides of the width direction of the conveyor frame.

[0022] Secondly, an automated processing technology for automotive parts according to the present invention, utilizing the aforementioned automated loading and turning equipment for automotive parts, includes the following steps: Top surface processing of automotive parts: The automotive parts are placed on conveyor frame one and enter a processing station. The automotive parts are processed by the processing equipment. After processing, the automotive parts are conveyed on conveyor frame one and arrive at the turnover frame. Automotive parts bottom surface processing: The automotive parts on the flipping frame are fixed by the positioning mechanism, and the flipping frame is rotated by the flipping mechanism to flip the automotive parts. Then the automotive parts are transported to another processing station and processed by the processing equipment.

[0023] Beneficial effects: By setting up a flipping mechanism and a positioning mechanism, the automotive parts on the conveyor frame are fixed by the positioning mechanism, and the automotive parts are flipped 180 degrees by rotating the flipping frame, so that the upper and lower sides of the automotive parts can be processed, thereby improving the processing efficiency of automotive parts.

[0024] The beneficial effects of this invention are as follows: By incorporating a flipping mechanism and a positioning mechanism, the automotive parts are first placed on a conveyor frame and moved to a processing station. The top surface of the automotive parts is then processed by the processing equipment. After processing, the automotive parts are conveyed back onto the conveyor frame and onto a flipping frame. The positioning mechanism then secures the automotive parts on the flipping frame. By rotating the flipping frame 180 degrees, the automotive parts are flipped and moved to another processing station. The processing equipment then processes the automotive parts on both the top and bottom surfaces, thus improving processing efficiency. Attached Figure Description

Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] Reference Figures 1-9 The present invention provides an automated loading and turning device for automotive parts, comprising a frame 10, a conveying mechanism, a turning mechanism, a longitudinal positioning component, a transverse positioning component, and a clamping component. A processing robot 8 for processing automotive parts is mounted on the frame 10.

[0037] In this embodiment, the length direction of the frame 10 is defined as the front-to-back direction, and the width direction of the frame 10 is defined as the left-to-right direction.

[0038] Reference Figure 1 and Figure 2 The conveying mechanism includes a first conveyor frame 20 and a second conveyor frame 21. The length directions of both the first conveyor frame 20 and the second conveyor frame 21 are perpendicular to the outer side of the panel corresponding to the length direction of the frame 10. The first conveyor frame 20 is used to convey the automotive parts to be processed, and the second conveyor frame 21 is used to convey the processed automotive parts to a specific workstation for the next processing step. In this embodiment, the first conveyor frame 20 is located on the front side, and the second conveyor frame 21 is located on the rear side.

[0039] Conveyor frame 1 (20) and conveyor frame 2 (21) have identical structures. Multiple conveyor rollers (22) are horizontally spaced on each conveyor frame, and a synchronous pulley (23) is fixedly connected to each conveyor roller (22). A synchronous belt (24) is driven to the outer side of each synchronous pulley (23), enabling the conveyor rollers (22) on each conveyor frame to rotate synchronously. One conveyor roller (22) on each conveyor frame is driven by a motor. Multiple tensioning pulleys (25) are also rotatably mounted on the conveyor frame. These tensioning pulleys (25) are positioned between two synchronous pulleys (23) and abut against the outer side of the synchronous belt (24), ensuring the tension of the synchronous belt (24) and maintaining the transmission effect between the synchronous pulleys (23) and the synchronous belt (24).

[0040] The area enclosed by the frame of the machine frame 10 is divided into two processing stations. The area corresponding to the machine frame 10 and the first conveyor frame 20 is the first processing station, and the area corresponding to the machine frame 10 and the second conveyor frame 21 is the second processing station.

[0041] Reference Figure 3 The flipping mechanism includes a sliding block 30, a first cylinder 31, a flipping frame 32, and a first motor 33.

[0042] Sliding blocks 30 are slidably installed on the two long crossbeams extending in the front-back direction of the frame 10. The sliding blocks 30 can slide in the front-back direction. A first cylinder 31 is installed on the long crossbeam of the frame 10. The telescopic part of the first cylinder 31 is fixedly connected to the sliding block 30. By telescopically extending the first cylinder 31, the sliding block 30 can be driven to slide back and forth.

[0043] When the sliding block 30 is in the initial position, it is located in the middle of the long crossbeam of the frame 10. When the first cylinder 31 drives the sliding block 30 to move, it can move to the rear side of the frame 10. In other words, the sliding block 30 can move to the second processing station.

[0044] A tilting frame 32 is rotatably mounted inside the sliding block 30. The tilting frame 32 can rotate along an axis extending in the left and right direction. The tilting frame 32 is rotatably engaged with the sliding block 30 via a rotating shaft. A first motor 33 is fixedly mounted on the sliding block 30. The output end of the first motor 33 is connected to the rotating shaft key on the tilting frame 32, thereby enabling the first motor 33 to drive the tilting frame 32 to rotate.

[0045] Initially, the tilting frame 32 is located at the first processing station. The conveyor frame 20 transports the automotive parts to be processed onto the tilting frame 32, where the parts are positioned by longitudinal positioning components, transverse positioning components, and clamping components. When the automotive parts need to be transported to the second processing station for processing, the first motor 33 drives the tilting frame 32 to rotate 180 degrees. At this time, the tilting frame 32 drives the automotive parts to flip over, and the first cylinder 31 drives the sliding block 30 to move backward, causing the tilting frame 32 to move backward to the second processing station. The automotive parts then undergo processing on the second side at the second processing station. After processing is completed, the parts are transported from the conveyor frame 21 to the next processing step. Then, the first motor 33 drives the tilting frame 32 to rotate and reset it.

[0046] Reference Figure 3 , Figure 4 and Figure 5 The longitudinal positioning assembly includes a support frame 40, a first lead screw 41, a second motor 42, a rotating roller 43, and a conveyor belt 44.

[0047] There are two support frames 40, which are symmetrically distributed on the tilting frame 32, and the support frames 40 can slide horizontally on the tilting frame 32 in the front-to-back direction. Each support frame 40 is equipped with a drive unit to drive its sliding.

[0048] The drive unit includes a first lead screw 41 rotatably mounted on a tilting frame 32, which is threadedly connected to a support frame 40. A second motor 42, which drives the rotation of the first lead screw 41, is mounted at one end of the first lead screw 41. The second motor 42 is fixedly mounted on the tilting frame 32, and its output end is fixedly connected to the first lead screw 41. When the second motor 42 drives the first lead screw 41 to rotate, the support frame 40 can slide back and forth along the tilting frame 32. Notably, the two support frames 40 can move towards each other; that is, they can move closer or further apart. Therefore, when the two support frames 40 are close together, they can clamp and position automotive parts in the front-to-back direction.

[0049] Multiple rotating rollers 43 are rotatably mounted on the inner surfaces of the two support frames 40 facing each other. The rotating rollers 43 can rotate along an axis extending in the front-back direction. Each support frame 40 is equipped with a motor that drives the rotating rollers 43 to rotate, and each support frame 40 has a conveyor belt 44 rotatably mounted on the rotating rollers 43. In this embodiment, the conveyor belt 44 is made of rubber.

[0050] The conveyor frame 20 transports the automotive parts to be processed onto the conveyor belt 44, with the front and rear ends of the automotive parts placed on the front and rear conveyor belts 44 respectively. Then, the second motor 42 drives the first lead screw 41 to rotate, causing the two support frames 40 to move closer to each other. Each of the opposing surfaces of the two support frames 40 has a clamping surface, thereby clamping the automotive parts through the clamping surfaces on the support frames 40, completing the positioning of the automotive parts in the front-rear direction.

[0051] Reference Figure 6 , Figure 7 and Figure 8 The lateral positioning assembly includes an adjusting frame 60, a fixing block 61, a second lead screw 62, a third lead screw 70, a third motor 71, a slider 72, a positioning plate 73, a lifting assembly, and a limit plate 79.

[0052] The adjusting frame 60 slides along the front-to-back direction on the tilting frame 32. The length of the adjusting frame 60 extends along the left-to-right direction, and the adjusting frame 60 is located between the two support frames 40, allowing it to slide back and forth between the two support frames 40. A fixing block 61 is fixedly installed at the left end of the adjusting frame 60. A second lead screw 62 is rotatably mounted on the tilting frame 32, and the second lead screw 62 is driven by a motor. The second lead screw 62 passes through the fixing block 61 and is threadedly connected to the fixing block 61. When the motor drives the second lead screw 62 to rotate, the adjusting frame 60 can slide back and forth on the tilting frame 32.

[0053] When the automotive parts are being processed, the flipping frame 32 flips the automotive parts over, at which point the adjusting frame 60 will be above the automotive parts. When processing the automotive parts, the adjusting frame 60 can be controlled to move in the front and back direction to avoid the adjusting frame 60 obstructing the position to be processed on the automotive parts.

[0054] The adjusting frame 60 has a long strip-shaped through hole running vertically through it. A third lead screw 70 is rotatably installed in the through hole along an axis extending in the left and right direction. That is, the axis of the third lead screw 70 is arranged horizontally in the left and right direction. A third motor 71 connected to the third lead screw 70 is installed on the fixing block 61, so that the third motor 71 can drive the third lead screw 70 to rotate.

[0055] A slider 72 is horizontally slidable within the through hole in the left-right direction. A third lead screw 70 passes through the slider 72, and the third lead screw 70 and the slider 72 are connected by a thread. Thus, when the third lead screw 70 rotates, it can drive the slider 72 to slide on the adjusting frame 60.

[0056] A positioning plate 73 is rotatably mounted on the slider 72 along its axis extending in the front-rear direction. In the initial state, the slider 72 and the positioning plate 73 are located on the side closer to the conveyor frame, and a limit plate 79 is fixedly installed on the side of the adjusting frame 60 away from the conveyor frame. When the conveyor frame 20 conveys the automotive parts onto the tilting frame 32, the lifting assembly first drives the positioning plate 73 to rotate to a horizontal state. After the automotive parts pass the positioning plate 73, the end of the automotive parts away from the conveyor frame 20 will abut against the limit plate 79. Then, the lifting assembly drives the positioning plate 73 to rotate to a vertical state, and the third lead screw 70 drives the slider 72 to slide, causing the slider 72 to move the positioning plate 73 toward the automotive parts. The limit plate 79 and the positioning plate 73 complete the lateral centering positioning of the automotive parts in the left-right direction.

[0057] Reference Figure 7 , Figure 8 and Figure 9 The lifting assembly includes a rotating column 74, an electric push rod 75, a slide rod 76, and a lifting frame 77.

[0058] Rotating posts 74 are fixedly installed on the right side of the positioning plate 73 near both the front and rear sides. The two rotating posts 74 are coaxially arranged, and the axis of the rotating posts 74 is parallel to the axis extending in the front-rear direction. The axis of the rotating posts 74 is also spaced apart from the axis of rotation of the positioning plate 73. It is particularly important to note that both the front and rear rotating posts 74 are located on the right side of the positioning plate 73 near the bottom.

[0059] A slide rod 76 is vertically slidably installed on the upper surface of the adjusting frame 60 near the front and rear sides (the front and rear sides of the through hole on the adjusting frame 60), and the axis of the slide rod 76 is arranged vertically. An electric push rod 75 is fixedly installed at the bottom of the adjusting frame 60. The telescopic part of the electric push rod 75 is fixedly connected to the slide rod 76, so that the electric push rod 75 can drive the slide rod 76 to rise and fall.

[0060] Lifting frames 77 are fixedly installed on the upper ends of the front and rear sliding rods 76. Sliding grooves 78 are opened on the opposite surfaces of the two lifting frames 77 in the front and rear directions. In this embodiment, the sliding grooves 78 pass through the lifting frames 77 from front to back. The front and rear rotating columns 74 are respectively inserted into the corresponding sliding grooves 78. The rotating columns 74 are used to stop and cooperate with one side wall of the sliding groove 78.

[0061] When the electric push rod 75 drives the lifting frame 77 to descend, the lifting frame 77 drives the rotating column 74 downward. Since the axis of the rotating column 74 is spaced apart from the axis of rotation of the positioning plate 73, the positioning plate 73 will flip on the slider 72 towards one side of the conveyor frame 20 until the positioning plate 73 rotates to a horizontal state. Thus, when the conveyor frame transports the automotive parts to the flipping frame 32, the automotive parts can pass over the horizontal positioning plate 73 and reach the flipping frame 32.

[0062] Similarly, after the automotive parts pass above the positioning plate 73, the electric push rod 75 drives the lifting frame 77 to rise, thereby pushing the rotating column 74 upward, causing the positioning plate 73 to rotate back to a vertical state. Then, the third lead screw 70 drives the slider 72 to slide, and the rotating column 74 will move in the slide groove 78, so that the slider 72 drives the positioning plate 73 to move towards the automotive parts. The limiting plate 79 and the positioning plate 73 complete the lateral centering positioning of the automotive parts in the left and right directions.

[0063] The clamping assembly is used to clamp the automotive parts onto the conveyor belt 44, so that the automotive parts can be prevented from falling off when the flipping frame 32 flips the automotive parts. At the same time, the clamping assembly also has a conveying function, which facilitates the transport of the processed automotive parts to the conveyor frame 21.

[0064] Reference Figure 4 and Figure 5 There are two sets of clamping components, which are respectively installed on two support frames 40. Each set of clamping components includes a translation unit and a clamping unit.

[0065] Reference Figure 5 The translation unit includes a side plate 50, a vertical plate 51, a second cylinder 52, and a translation frame 53.

[0066] A side plate 50 is horizontally welded onto the support frame 40. A vertically mounted upright plate 51 is fixedly installed at the edge of the upper surface of the side plate 50. A horizontally sliding translation frame 53 is mounted on the upright plate 51, and the translation frame 53 can slide in the front-back direction. A second cylinder 52 is also fixedly installed on the upright plate 51. The telescopic part of the second cylinder 52 is fixedly connected to the translation frame 53, so that the second cylinder 52 can drive the translation frame 53 to slide. A clamping unit is installed on the translation frame 53. When the second cylinder 52 extends, it can drive the clamping unit to move directly above the conveyor belt 44; when the second cylinder 52 retracts, it can drive the clamping unit to move to one side of the conveyor belt 44. Therefore, when processing the first surface of the automotive parts, the obstructed area can be reduced, ensuring the processing effect of the automotive parts and improving the practicality of the device.

[0067] Reference Figure 5 The clamping unit includes a third cylinder 54, a clamping frame 55, and a clamping band 56.

[0068] A third cylinder 54 is fixedly mounted on the upper surface of the translation frame 53. A clamping frame 55 is fixedly mounted on the telescopic part of the third cylinder 54. Multiple guide rollers (not shown in the figure) are rotatably mounted on the inner side of the clamping frame 55. The guide rollers rotate along an axis extending in the front-rear direction. A clamping belt 56 is driven and mounted on the guide rollers. In this embodiment, the clamping belt 56 is made of rubber and is arranged parallel to the horizontal part of the conveyor belt 44. The guide rollers are driven by a motor, which enables the guide rollers to drive the clamping belt 56 to rotate. When the third cylinder 54 drives the clamping belt 56 to descend, it can press the car parts onto the conveyor belt 44, thereby fixing the car parts vertically. This prevents the car parts from falling when the flipping frame 32 flips the car parts. After the flipped car parts have been processed, the rotation of the clamping belt 56 can transport the car parts to the conveyor frame 21.

[0069] During the first-side processing of the automotive part, the second cylinder 52 is in a retracted state, and the clamping belt 56 is located on one side above the conveyor belt 44. During the first-side processing, the upper surface of the automotive part is unobstructed. When the automotive part needs to be flipped, the second cylinder 52 extends, moving the clamping belt 56 directly above the conveyor belt 44. Then, the third cylinder 54 lowers the clamping belt 56, pressing the automotive part firmly onto the conveyor belt 44. The flipping frame 32 then flips the automotive part to process the other side. During the second-side processing, the motor drives the second lead screw 62 to rotate, causing the adjusting frame 60 to slide back and forth on the flipping frame 32. By moving the position of the adjusting frame 60, it is prevented from obstructing the processing area on the automotive part.

[0070] The implementation principle of the automated loading and turning device for automotive parts of the present invention is as follows: In the initial state, the turning frame 32 is located at the first processing station. The automotive parts are first placed on the conveyor frame 20 and enter a processing station. The automotive parts are conveyed on the conveyor frame 20. When the automotive parts reach the tilting frame 32, firstly, the electric push rod 75 drives the lifting frame 77 to descend, and at the same time, the lifting frame 77 drives the rotating column 74 downward. Since the rotating column 74 is located on the side of the positioning plate 73 close to the conveyor frame, the positioning plate 73 will flip on the slider 72 towards the side of the conveyor frame 20 until the positioning plate 73 rotates to a horizontal state, thus facilitating the transportation of the automotive parts to the tilting frame 32 via the positioning plate 73. After the automotive parts pass through the positioning plate 73, the end of the automotive parts in the direction of movement will abut against the limiting plate 79. Similarly, the electric push rod 75 drives the lifting frame 77 to rise, thereby pushing the rotating column 74 upward, causing the positioning plate 73 to rotate back to a vertical state. Then the third lead screw 70 drives the slider 72 to slide, and the rotating column 74 moves in the slide groove 78, so that the slider 72 drives the positioning plate 73 to move towards the car parts. The limiting plate 79 and the positioning plate 73 complete the lateral centering positioning of the car parts in the left and right directions.

[0071] At this time, the front and rear ends of the car parts are placed on the front and rear conveyor belts 44 respectively. Then the second motor 42 drives the first lead screw 41 to rotate, so that the two support frames 40 move inward at the same time, thereby clamping the car parts and completing the positioning of the car parts in the front and rear directions. Then the top surface of the car parts is processed by the processing robot 8. After the top surface of the automotive part is processed, the second cylinder 52 extends, driving the clamping belt 56 to move directly above the conveyor belt 44. Then, the third cylinder 54 drives the clamping belt 56 to descend, pressing the automotive part onto the conveyor belt 44. Next, the first motor 33 drives the flipping frame 32 to flip 180 degrees. At this time, the flipping frame 32 is located at the second processing station, allowing the flipping frame 32 to flip the automotive part. Then, the first cylinder 31 drives the sliding block 30 to move backward, causing the flipping frame 32 to move backward to the second processing station. The processing robot 8 processes the bottom surface of the automotive part. During the processing of the second surface, the motor drives the second lead screw 62 to rotate, causing the adjusting frame 60 to slide back and forth on the flipping frame 32. By moving the position of the adjusting frame 60, the adjusting frame 60 is prevented from obstructing the processing position on the automotive part. After the bottom surface is processed, the clamping belt 56 rotates to transport the automotive parts to the second conveyor frame 21. Finally, the automotive parts are transported to the next processing step via the second conveyor frame 21. Then, the first motor 33 drives the tilting frame 32 to tilt and reset it, and this cycle continues.

[0072] Reference Figures 1-9 The present invention also provides an automated processing technology for automotive parts, which includes the following steps: Top surface processing of automotive parts: The automotive parts are placed on the conveyor frame 20 and enter a processing station. The automotive parts are processed by the processing equipment. After processing, the automotive parts are conveyed on the conveyor frame 20 and arrive at the tilting frame 32. Automotive parts bottom surface processing: The automotive parts on the flipping frame 32 are fixed by the positioning mechanism, and the flipping frame 32 is rotated by the flipping mechanism to flip the automotive parts. Then the automotive parts are transported to another processing station and processed by the processing equipment.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
