Technical Field

[0001] This invention relates to the field of new energy vehicle technology, specifically to an automatic feeding device for new energy vehicle workpieces. Background Technology

[0002] When producing new energy vehicles, the body frame is generally made of materials such as aluminum alloy and steel plate to ensure the vehicle is lightweight while ensuring safety.

[0003] For example, Chinese patent CN204713983U discloses an automatic workpiece feeding device, including a feeding belt, a feeding hopper, and a feeding motor that drives the feeding belt. The feeding belt is equipped with a slanted hook plate. An inlet is located at the contact point between the feeding belt and the feeding hopper, and an outlet is located at the discharge point. A transition plate is located directly below the outlet. The automatic feeding function is achieved through the hook plate in conjunction with the feeding belt and feeding motor. The device has a simple structure and low manufacturing cost. Furthermore, the sequential feeding via the dividing plate ensures neat workpiece arrangement and improves the accuracy of workpiece counting. However, in the aforementioned device, the preceding and following conveyor lines are arranged perpendicularly. During the upward conveying of workpieces, there is a risk of workpieces falling off or moving. To mitigate this risk, the workpieces need to be secured. Therefore, an automatic workpiece feeding device for new energy vehicles is proposed to address the aforementioned problems. Summary of the Invention

Above the rectangular through hole, each clamp plate has a first connecting rod connected to both ends of its bottom, extending movably through the rectangular through hole into the rectangular groove. A fixing rod is movably inserted into the bottom of each first connecting rod, with both ends of the fixing rod fixedly connected to the inner wall of the rectangular groove. A first spring is sleeved on the outer wall of the fixing rod, with both ends of the first spring fixedly connected to the inner wall of the rectangular groove and one side of the first connecting rod, respectively. Each clamp plate has a mounting groove at its top, and a movable clamp plate is installed on the inner wall of the mounting groove. A first push rod is fixedly connected to the bottom of the movable clamp plate, with the bottom of the first push rod movably penetrating through the clamp plate. A rectangular through-hole extends into the inner wall of a rectangular groove. A wedge-shaped block is connected to the bottom of the inner wall of the rectangular groove. The bottom of the extended end of the first push rod is in contact with the top of the wedge-shaped block. A pushing mechanism is provided inside the operating box to push the workpiece on the lifting plate out of the material. A steering mechanism is provided on the left support leg to rotate the workpiece 90 degrees after it is discharged. Two fixing rods are provided and are fixedly connected to the rectangular groove directly below the two sets of rectangular through-holes on the left and right sides, respectively. Rectangular rods are fixedly connected to the right sides of the two first connecting rods on the right side, and a lower adjusting block is fixedly connected to the right side of the rectangular rods. The right side of the lower operating platform... A support block is fixedly connected between two lower adjusting blocks to push the two lower adjusting blocks away from each other. A machine box is fixedly connected to the right side of the operation box, and an upper adjusting block is connected to the bottom. A pulley group is provided between the machine box and the lifting plate. One end of the pulley group is installed in the machine box, and the other end is installed on the lifting plate. A circular groove is opened at the bottom of the movable clamping plate. A limit rod and a fourth spring are provided on the inner wall of the circular groove. The bottom of the limit rod is fixedly connected to the mounting groove and inserted into the circular groove. The fourth spring is sleeved on the outer wall of the limit rod and fixedly connected to the mounting groove and the circular groove.The pulley system includes three fixed pulleys, one movable pulley, and a wire rope. One fixed pulley is installed inside the machine housing, and the other two fixed pulleys are installed on the right side of the control box and the support leg. One end of the wire rope is wound around the fixed pulley inside the machine housing and connected sequentially to the fixed pulley in the control box. It is then fixedly connected to the movable block, and after suspending the movable pulley, it is wound around the fixed pulley of the support leg and fixedly installed on the lifting plate. The right side of the support leg has a movable groove, and a counterweight is fixedly connected to the bottom of its movable pulley, with one end of the counterweight slidably connected to... Within the movable slot, the lifting block is pushed upward by the cylinder inside the support leg, thereby pushing the lifting plate upward. During this upward movement, the two lower adjusting blocks disengage from the support block. Then, under the push of the first spring, the first connecting rods on the front and rear sides are pushed closer together against the outer wall of the fixed rod, which in turn pushes the two clamping plates closer together. Simultaneously, during this close movement, under the pressure of the wedge-shaped block, the first push rod moves upward, further pushing the movable clamping plate upward, thereby increasing the clamping height and preventing the workpiece from falling off during the lifting process.

[0006] Preferably, the pushing mechanism includes: a round rod, a second spring, a movable block, a second push rod, and a pushing plate. The round rod is fixedly connected to the inner wall of the operating box. The second spring and one side of the movable block are sleeved on the outer wall of the round rod. A pushing hole is opened at the bottom of the inner wall of the operating box. The bottom of the movable block movably passes through the pushing hole and is fixedly connected to the right side of the second push rod. The right side of the pushing plate is fixedly connected to the left side of the second push rod for pushing the workpiece on the lifting plate. The pushing mechanism further includes: a telescopic push plate, a T-shaped slider, and a first movable hole. Two first movable holes are provided and are radially opened at the bottom of the inner wall of the operating box on both sides of the pushing hole. Rectangular movable grooves are opened on the front and rear sides of the pushing plate. The inner wall of each rectangular movable groove is slidably connected to the outer wall of the telescopic push plate, and the top of the telescopic push plate is fixedly connected to the bottom of the T-shaped slider. The T-shaped slider is slidably connected inside the first movable hole. The front and rear sides of the block are respectively connected to the second connecting rod, and the outer wall of the second connecting rod is movably fitted with the first push block. The outer wall of the second connecting rod is fitted with the third spring and is located on the side of the first push block away from the movable block. The inner wall of the operating box is fixedly connected to the right side of the inner wall, and the outer wall of the operating box is provided with the limit hole. The right side of the first push block is fixedly connected to the locking block, and the locking block is locked in the limit hole. When the lifting plate moves upward to the top, its two lower adjusting blocks contact the upper adjusting block and continuously squeeze and push the two lower adjusting blocks away from each other, thereby driving the two clamping plates away and contacting the locking block to push them out of the limit hole. Under the reset action of the second spring, the movable block is pulled to move on the outer wall of the round rod, driving the second push block below the movable block to drive the push plate to move. At the same time, during the pushing process, the T-shaped slider moves in the radial first movable hole, thereby expanding the pushing length of the two telescopic push plates to push the workpiece.

[0007] Preferably, the steering mechanism includes: an upper operating platform, a rotating platform, a horseshoe-shaped block, a guide block, a rectangular block, a rotating shaft, a connecting block, a connecting plate, a compression hemisphere, a movable rod, a slide rail, and a second push block. The horseshoe-shaped block is fixedly connected to the bottom of the upper operating platform. Two guide blocks are provided and fixedly connected to the inner side of the horseshoe-shaped block respectively. The upper operating platform is fixedly connected to the top of the two left support legs. A second movable hole is provided at the top of the upper operating platform, and a movable block is slidably connected in the movable hole. The top of the rotating shaft passes through the rectangular block and the movable block in sequence. Hinged to the bottom of the rotating platform, the connecting block is rotatably connected to the outer wall of the rotating shaft via bearings. The connecting plate is fixedly connected to the bottom of the horseshoe-shaped block. The bottom of the extrusion hemisphere is movably inserted into the connecting plate via an extension rod, and the extrusion hemisphere is pushed upward by a first return spring sleeved on the outer wall of the extension rod. The bottom of the rectangular block has four grooves that intermittently contact the extrusion hemisphere. Two slide rails are provided and connected to the front and back of the inner wall of the operating box, respectively. A T-shaped slide groove and a slide channel are provided on one side of the movable rod. The movable rod is slidably connected to the slide rail via the T-shaped groove. The second push block is fixedly connected to the end of the second connecting rod away from the movable block, and the other end of the second push block is in contact with the groove. The left side of the movable rod moves through the operating box and extends outward, with its extended end connected to a contact plate located on the right side of the rotating platform. The steering mechanism also includes: a movable plate, a pressing rod, and a pushing rod. One end of the pressing rod is fixedly connected to the bottom of the upper operating table via a mounting rod, and the pressing rod is movably sleeved on the outer wall of the mounting rod. One end of the movable plate is fixedly connected to the connecting block. The top of the movable plate contacts the bottom of the extrusion rod through a hemisphere. A through hole is provided on the top of the upper operating platform, and the push rod is set on the top of the upper operating platform. The bottom of the push rod is movably connected to the top of the extrusion rod through the through hole via a support rod. An arc-shaped protrusion is provided at one end of the extrusion rod. One side of the upper operating platform is inclined. A protective box is installed at the bottom of the upper operating platform. The bottom of the protective box is fixedly connected to the left support leg via a support rod. A second return spring is fixedly connected between the connecting block and the inner wall of the horseshoe block.As the movable block moves, it pushes the second connecting rod, which in turn moves the second push block. When the push block reaches halfway along the movable rod, the second push block begins to push the movable rod along the slide rail. This, in turn, moves the contact plate against the circular upper operating table, causing the movable block to move within the movable hole. This pushes the lower rectangular block to the left, where it contacts the guide block. The rollers on the guide block then contact the rectangular block, causing it to rotate 90 degrees. This disengages the groove at the bottom of the rectangular block from the extrusion hemisphere, thus rotating the workpiece on the rotating platform 90 degrees. Simultaneously, as the rectangular block moves, it moves the movable plate, which contacts the extrusion rod and presses it against the outer wall of the mounting rod. This pushes the push rod upwards, tilting the hinged rotating platform and allowing the 90-degree rotated workpiece to slide onto the upper operating table.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This automatic workpiece feeding device for new energy vehicles uses a cylinder inside the support leg to push the lifting block, thereby pushing the lifting plate upward. During the upward movement, the two lower adjusting blocks disengage from the support block. Then, under the push of the first spring, the first connecting rods on the front and rear sides are pushed closer to each other on the outer wall of the fixed rod, which in turn pushes the two clamping plates closer to each other, thus clamping the workpiece placed on the lifting plate and preventing the workpiece from falling off the lifting plate, improving the stability during lifting. At the same time, during the process of approaching each other, under the pressure of the wedge block, the first push rod is pushed upward, which in turn pushes the movable clamping plate upward, thereby increasing the clamping height and thus increasing the contact area for clamping the workpiece and improving the clamping effect.

[0010] 2. In this automatic workpiece feeding device for new energy vehicles, when the lifting plate moves upward to the top, its two lower adjusting blocks contact the upper adjusting block and continuously squeeze and push the two lower adjusting blocks away from each other, thereby causing the two clamping plates to move away and releasing the workpiece clamping. It then contacts the locking block to push it out of the limiting hole. Under the reset action of the second spring, the movable block is pulled to move on the outer wall of the round rod, which drives the second push block below the movable block to move the push plate, thereby pushing the workpiece on the lifting plate to achieve the purpose of unloading. At the same time, during the pushing process, the T-shaped slider moves in the radial first movable hole, thereby expanding the pushing length of the two telescopic push plates, thereby achieving a more comprehensive pushing of the workpiece.

[0011] 3. This automatic feeding device for new energy vehicle workpieces moves by pushing the second connecting rod when the movable block moves, which in turn drives the second pusher block to move. When the pusher block reaches halfway along the movable rod, the second pusher block begins to push the movable rod to move on the slide rail, which then moves through the contact plate and the circular upper operating table. This causes the movable block to move within the movable hole, pushing the rectangular block below to the left and into contact with the guide block. The rollers on the guide block then contact the rectangular block, causing it to rotate 90 degrees. This causes the groove at the bottom of the rectangular block to disengage from the extrusion hemisphere, thus achieving rotation. This allows the workpiece on the rotating platform to be rotated 90 degrees, facilitating subsequent stacking. Simultaneously, during the movement of the rectangular block, the movable plate moves, contacting the extrusion rod and extruding it onto the outer wall of the mounting rod. This pushes the pusher rod upward, causing the hinged rotating platform to tilt. This allows the workpiece, which has rotated 90 degrees, to slide onto the upper operating table, further facilitating the workpiece's sliding to a designated location for stacking.

The two clamping plates 10 are close to each other to clamp the workpiece placed on the lifting plate 3, thereby preventing the workpiece from falling off the lifting plate 3 and improving the stability during lifting. The inside of the operation box 4 is provided with a pushing mechanism 5, which is used to push the workpiece on the lifting plate 3 out. The left support leg 2 is provided with a steering mechanism 6, which is used to rotate the workpiece ninety degrees after it is discharged.Two fixing rods 7 are provided and are fixedly connected to the rectangular grooves located directly below the two sets of rectangular through holes on the left and right sides. Rectangular rods 15 are fixedly connected to the right sides of the two first connecting rods 9 on the right side, and lower adjusting blocks 16 are fixedly connected to the right sides of the rectangular rods 15. A support block 17 is fixedly connected to the right side of the lower operating platform 1, located between the two lower adjusting blocks 16, for pushing the two lower adjusting blocks 16 away from each other. A machine box 19 is fixedly connected to the right side of the operating box 4, and an upper adjusting block 18 is connected to its bottom.

The pulley group 20 includes: three fixed pulleys, one movable pulley and a wire rope. One fixed pulley is installed in the machine box 19, and the other two fixed pulleys are installed on the right side of the operating box 4 and the support leg 2. One end of the wire rope is wound around the fixed pulley in the machine box 19 and connected to the fixed pulley of the operating box 4 in sequence. Then it is fixedly connected to the movable block 503, and after suspending the movable pulley, it is wound around the fixed pulley of the support leg 2 and fixedly installed on the lifting plate 3. The right side of the support leg 2 is provided with a movable groove. The bottom of its movable pulley is fixedly connected to a counterweight, and one end of the counterweight is slidably connected in the movable groove.The pushing mechanism 5 includes: a round rod 501, a second spring 502, a movable block 503, a second push rod 504, and a pushing plate 505. The round rod 501 is fixedly connected to the inner wall of the operating box 4. The second spring 502 and the movable block 503 are sleeved on one side of the outer wall of the round rod 501. A pushing hole is opened at the bottom of the inner wall of the operating box 4. The bottom of the movable block 503 movably passes through the pushing hole and is fixedly connected to the right side of the second push rod 504. The right side of the pushing plate 505 is fixedly connected to the left side of the second push rod 504, and is used to push the workpiece on the lifting plate 3. The pushing mechanism 5 also includes: a telescopic push plate 506, a T-shaped slider 507, and a first movable hole 508. Two first movable holes 508 are provided and are radially opened at the bottom of the inner wall of the operating box 4 on both sides of the pushing hole. Rectangular movable grooves are opened on the front and rear sides of the pushing plate 505. The inner wall of each rectangular movable groove is slidably connected to the outer wall of the telescopic push plate 506, and the telescopic push plate 506... The top is fixedly connected to the bottom of the T-shaped slider 507, which is slidably connected inside the first movable hole 508. It pushes the workpiece on the lifting plate 3 to achieve the purpose of discharging. Simultaneously, during the pushing process, the T-shaped slider 507 moves within the radial first movable hole 508, thereby expanding the pushing length of the two telescopic push plates 506, thus achieving more comprehensive pushing of the workpiece. The front and rear sides of the movable block 503 are respectively connected to second connecting rods 509, and the outer wall of the second connecting rod 509 is movably fitted with a first push block 5010. The outer wall of the second connecting rod 509 is fitted with a third spring 5011 located on the side of the first push block 5010 away from the movable block 503. The inner right wall of the operating box 4 is fixedly connected to a pressing block 5013, and the outer right wall of the operating box 4 has a limit hole. The right side of the first push block 5010 is fixedly connected to a locking block 5012, which engages within the limit hole.

[0023] Working principle: The cylinder is activated, which pushes the lifting block to move, thereby pushing the lifting plate 3 connected to one side upward. During the upward movement, the two lower adjusting blocks 16 disengage from the support block 17. At this time, under the compression of the first spring 8, the first connecting rods 9 on the front and rear sides are pushed to move on the fixed rod 7, thereby pushing the clamping plates 10 closer together to clamp the workpiece placed on the lifting plate 3. At the same time, during the movement, the movable clamping plate 11 slides on the wedge block 12 through the first push rod connected to the bottom. By continuously raising the movable clamping plate 11, the clamping height of the workpiece is changed to achieve a better clamping effect. During the upward movement, the wire rope on the pulley block 20 is continuously pulled by the counterweight and the length of the wire rope is adjusted by the movable pulley. After the two lower adjusting blocks 16 contact the upper adjusting block 18, they move away from each other and push the clamping plates 10 away from each other, achieving the purpose of disengaging from clamping.

[0024] When the inclined outer walls of the two lower adjusting blocks 16 contact the locking block 5012, they will push the locking block 5012 to move to both sides, causing the locking block 5012 to disengage from the limiting hole. Under the reset action of the second spring 502, the movable block 503 is pulled to move on the outer wall of the round rod 501, thereby pushing the second push rod 504 to drive the pusher plate 505 to move. During its movement, the two T-shaped sliders 507 move within the first movable hole 508, thereby pushing the two telescopic push plates 506 away from each other, thus increasing the pushing range. Then, during the pushing movement, the movable block... 503 moves, pulling the wire rope to move, which in turn pulls the movable pulley upward, changing the trajectory of the wire rope. During the downward movement of its lifting plate 3, since the counterweight is limited on the support leg 2, it moves through the lifting plate 3 to pull the wire rope downward, which in turn pulls the movable block 503 connected to the other end to move to the right. After the locking block 5012 moves to the right side and contacts the pressing block 5013, it generates pressure, allowing it to enter the limiting hole. Then, under the pressure of the third spring 5011, it pushes the first push block 5010 to move, thereby locking the locking block 5012 into the limiting hole and restoring it.

[0026] Working principle: During the pushing process, the movable block 503 moves to the left, driving the second connecting rod 509 to move, which in turn drives the second pushing block 615 on one side to move to the left, thus moving it within the groove of the movable rod 613. When it moves to the other side of the groove, the continuous leftward movement of the movable block 503 pushes the movable rod 613 to move, which in turn drives the contact plate to move to the left, making it contact with the rotating platform 602. This pushes the rotating platform 602 to the left. During the movement, the movable block moves within the groove, causing the rectangular block 605 to move to the left and contact the roller on the guide block 604 on the left, thus squeezing the rectangular block 605 to rotate. This, in turn, drives the overall rotating shaft 606 and the rotating platform 602 to rotate. After the rotation, the hinge point rotates, aligning with the second movable hole for rotation. During the movement of the connecting block 607, it contacts the squeezing rod 611, generating upward squeezing, which in turn pushes the squeezing rod 611 upward, thus pushing the... The push rod 612 connected to the top moves upward, pushing one side of the rotating platform 602 to rotate around the hinge point, thereby tilting it to facilitate the sliding of the 90-degree rotated workpiece onto the upper operating table 601 for rapid material stacking. Then, when the rotating platform 602 is not subjected to force by the movable rod 613, the connecting block 607 is pulled to the right by the second return spring. When the rectangular block 605 is no longer in contact with the guide block 604, its bottom contacts the edge of the bottom groove through the extrusion hemisphere 609. Under the action of the first return spring, the extrusion hemisphere 609 is pushed upward and enters the groove, causing it to drive the rectangular block 605 to generate a deflection angle. During the reset process, the rectangular block 605 is pulled to continue rotating with the right rectangular block 605. When the rectangular block 605 continues to move to the left and disengages from the right rectangular block 605, it continues to generate a deflection angle through the extrusion hemisphere 609, facilitating the next flip. At the same time, the rotating platform 602 at the top rotates 180 degrees to achieve cyclic material stacking.
