Description

Technical Field

[0001] The invention relates to a punching and embossing feeding device, belonging to the technical field of automobile welding. Background Art

[0002] When welding the automotive body-in-white, high weld quality is required. ARPLAS welding is often used where the welding position is on the narrow edge. ARPLAS welding is an excellent welding technology for solving the problem of narrow edge welding of door hems and rear runners of side panels. It can form connections with small indentations and good appearance quality while ensuring welding strength and no deformation.

[0003] Before ARPLAS welding, a bulge must be punched into a part to concentrate welding energy. This means that ARPLAS welding requires a bulging device. Currently, this device includes a bulging gun, which is typically used by a robot carrying the bulging gun. The bulging process involves a robot grabbing the workpiece from the unembossed workpiece placement area and then bringing it to a fixed bulging device. The bulging robot, carrying the bulging gun, embosses the workpiece once it's in place. The robot then places the bulged workpiece on a designated placement table or bin. Because the bulging gun is fixed, the entire workpiece transfer process is performed by the robot. This process is time-consuming and time-consuming, making it difficult to meet the high-speed production requirements. Summary of the Invention

[0004] The present invention aims to solve the deficiencies in the prior art and provides a embossing feeding device.

[0005] The present invention solves the above-mentioned technical problem with the following technical solution: a device for embossing and feeding a workpiece, comprising a rotary worktable, and further comprising a first workstation and a second workstation, wherein the first workstation and the second workstation are respectively arranged at diagonal positions of the rotary worktable, the rotary worktable is provided with a clamping unit corresponding to the first workstation and the second workstation, the clamping unit being used to position and press a workpiece, and a embossing device for embossing the workpiece is provided at the second workstation;

[0006] The clamp unit includes a positioning mechanism and at least one pressing mechanism, wherein the positioning mechanism includes a positioning frame and at least one positioning pin provided on the positioning frame and corresponding to a positioning hole on the workpiece;

[0007] The clamping mechanism includes a clamping frame, a lower support block, an upper clamping block and a clamping cylinder that drives the upper clamping block to cooperate with the lower support block to clamp or release the workpiece. The lower support block is arranged on the clamping frame, the clamping cylinder is provided with a clamping arm, and the upper clamping block is arranged on the clamping arm.

[0008] The beneficial effects of the present invention are as follows: the fixture unit on the first workstation is manually loaded, the positioning hole of the specific workpiece cooperates with the positioning pin to position the workpiece, the clamping cylinder is actuated, and the upper clamping block swings down under the clamping arm to press the workpiece, the rotary table rotates 180 degrees, and the workpiece is transferred to the second workstation. The robot can carry the embossing device to perform embossing on the positioned workpiece at the second workstation. At this time, the fixture unit at the diagonal position of the rotary table is transferred to the first workstation to load the workpiece at the same time. After the workpiece is embossed, the clamping cylinder is actuated to move the upper clamping block away from the lower support block, so that the workpiece can be removed and discharged. After that, the rotary table can be rotated 180 degrees in the opposite direction, and the fixture unit after discharge on the rotary table is transferred to the loading position for loading, and the fixture unit that has been loaded is transferred to the embossing processing position for embossing. The invention has a simple structure and is easy to operate. It can load workpieces while the embossing process is in progress, and the workpieces before and after the embossing will not be confused. It is not only safe and reliable, but also saves time and improves the embossing cycle to meet the production requirements of high-cycle embossing of workpieces. It also reduces processing costs and shortens debugging time.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the positioning mechanism also includes a positioning cylinder for driving the positioning pin to move, the cylinder body of the positioning cylinder is arranged on the positioning frame, and the piston rod of the positioning cylinder is connected to the positioning pin.

[0011] The beneficial effect of adopting the above further solution is that the positioning pin can be extended and retracted under the action of the positioning cylinder. When loading the workpiece, the positioning pin is extended to position the workpiece. After the workpiece punching and embossing is completed, the positioning pin can be retracted, which is conducive to the smooth discharge of the workpiece.

[0012] Furthermore, a guardrail is provided in the middle of the rotary workbench, the first workstation is located on one side of the guardrail, and the second workstation is located on the other side of the guardrail.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the worker loads the workpiece at the first workstation, and then the rotary worktable rotates 180 degrees. The workpiece is transferred to the second workstation under the action of the rotary worktable. The second workstation is the embossing processing station, and an embossing device such as a embossing gun is used to perform embossing operations on the workpiece. The guardrail can be used for manual loading and embossing of workpieces, making the embossing and picking device safer and more reliable. In addition, workpieces are loaded on one side of the guardrail and unloaded by embossing on the other side, that is, workpieces are loaded at the first workstation and the second workpiece is embossed and discharged, avoiding confusion between the workpieces before and after embossing.

[0014] Furthermore, it also includes a turning mechanism for discharging the workpiece after embossing and a receiving mechanism for receiving the workpiece, and the receiving mechanism is arranged on the discharge port side of the turning mechanism.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that after the embossing operation of the workpiece is completed, the clamping unit releases the workpiece, the flipping mechanism is activated to make the workpiece detach from the clamping unit, and the workpiece can be tilted to the side of the discharge port, and the material is received by the receiving mechanism on the side of the discharge port, avoiding the unsafe situation of manually removing the embossed workpiece directly at the embossing processing position.

[0016] Furthermore, the flip mechanism includes a flip bracket, a tray, a pair of connecting rod mechanisms arranged between the flip bracket and the tray, and a flip cylinder. The tray is provided with an avoidance notch on the inner side close to the clamp unit, and the tray is provided with discharge blocks on both sides of the avoidance notch.

[0017] The connecting rod mechanism includes a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod are arranged in parallel. The middle part of the first connecting rod is hinged to the flip bracket. One end of the first connecting rod is hinged to the tray, and the other end is connected to the piston rod of the flip cylinder; one end of the second connecting rod is hinged to the tray, and the other end is hinged to the flip bracket.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the pallet must be able to guide the embossed workpiece out of the material while avoiding interference with the fixture unit. Therefore, an avoidance slot is provided so that the discharge block on the inside of the pallet can be located on the inside of the workpiece of the fixture unit. When the pallet is tilted under the drive of the flip cylinder and the connecting rod mechanism, the embossed workpiece can be guided to the discharge port side, and the embossed workpiece can be placed on the receiving mechanism along the pallet with high inside and low outside; then the workpiece can be taken out manually from the receiving mechanism, and the material retrieval is safer and more reliable.

[0019] Furthermore, the flip bracket includes a pair of frames, which are connected by a first hinge shaft and a second hinge shaft, the first connecting rod is connected to the flip bracket through the first hinge shaft, and the second connecting rod is connected to the flip bracket through the second hinge shaft.

[0020] The beneficial effect of adopting the above further solution is that the hinge shaft is rotatably set on the flip bracket, and the connecting rod is connected to the hinge shaft, which is not only convenient for connection, but also can further increase the supporting strength between the connecting rod mechanisms, thereby ensuring the stability of the tray of the flip mechanism.

[0021] Furthermore, at least two pulley rollers are provided on the tray, and the pulley rollers include a roller seat and a plurality of pulleys rotatably provided on the roller seat.

[0022] The beneficial effect of adopting the above-mentioned further scheme is that under the action of the flipping mechanism, the embossed workpiece is discharged under the action of the flipped and tilted pallet. In order to further reduce the friction between the workpiece and the supporting surface of the pallet, a pulley roller can be set on the supporting surface of the pallet. The workpiece is supported on the pulley, and the rolling friction between the workpiece and the pallet is more conducive to the discharge of the workpiece.

[0023] Furthermore, the material receiving mechanism includes an inclined section slide and a horizontal section slide connected to the lower position of the inclined section slide, and a guard plate is provided on the periphery of the horizontal section slide.

[0024] The beneficial effect of adopting the above-mentioned further scheme is that the inclination angle of the inclined section slide can be adjusted as needed to ensure that the workpiece can slide smoothly to the position of the horizontal section slide. The workpiece after punching can fall onto the inclined section slide of the material receiving mechanism through the flipping mechanism, and enter the horizontal section slide under the guidance of the inclined section slide. The horizontal section slide is the workpiece picking position, where the processed workpiece can be manually taken out.

[0025] Furthermore, the rotating worktable is arranged on the bottom frame, and at least one clamping mechanism is provided between the rotating worktable and the bottom frame for positioning the rotating worktable after it is rotated into place.

[0026] The beneficial effect of adopting the above further scheme is that when the rotary worktable is rotated into position, if the workpiece to be processed is transferred to the second station to wait for embossing operation, the rotary worktable can be clamped and positioned by the clamping mechanism, further ensuring the stability of the workpiece when the embossing device performs the embossing operation.

[0027] Furthermore, the clamping mechanism includes a locking block, a fixed limit block for clamping the locking block, a movable limit block and a clamping cylinder for driving the movable limit block to move. The locking block is arranged on the rotating workbench, the fixed limit block is arranged on the bottom frame through a column, the clamping cylinder is arranged on the bottom frame, a clamping pressure arm is provided on the clamping cylinder, and the movable limit block is arranged on the clamping pressure arm.

[0028] The beneficial effect of adopting the above-mentioned further solution is that the clamping cylinder is actuated to drive the clamping pressure arm to swing. The limit block provided on the clamping pressure arm can be swung toward the locking block to limit it, thereby more stably positioning the rotary table after it is rotated into position, or swinging away from the locking block to prevent the limit block from interfering with the rotation of the rotary table. The rotary table can rotate back and forth 180 degrees. The locking block is provided at the bottom of the rotary table. After the rotary table is rotated into position, one side of the locking block contacts the fixed limit block. The movable limit block acts on the other side of the locking block under the action of the clamping cylinder. The fixed limit block and the movable limit block cooperate to clamp the locking block, which can hook and position the rotary table after it is rotated into position, thereby meeting the stability requirements of the punching operation.

[0037] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] like Figure 1-Figure 7 As shown, a device for embossing and feeding a workpiece includes a rotary worktable 1, and also includes a first workstation 8 and a second workstation 9. The first workstation 8 and the second workstation 9 are respectively arranged at diagonal positions of the rotary worktable 1. The rotary worktable 1 is provided with a clamping unit corresponding to the first workstation 8 and the second workstation 9. The clamping unit is used to position and press the workpiece. The second workstation 9 is provided with a embossing device for embossing the workpiece.

[0039] The clamp unit includes a positioning mechanism 3 and at least one pressing mechanism 2, wherein the positioning mechanism 3 includes a positioning frame 301 and at least one positioning pin 302 provided on the positioning frame 301 and corresponding to a positioning hole on the workpiece;

[0040] The clamping mechanism 2 includes a clamping frame 201, a lower support block 202, an upper clamping block 203 and a clamping cylinder 204 that drives the upper clamping block 203 to cooperate with the lower support block 202 to clamp or loosen the workpiece. The lower support block 202 is arranged on the clamping frame 201, the clamping cylinder 204 is provided with a clamping arm 2041, and the upper clamping block 203 is arranged on the clamping arm 2041.

[0041] The first workstation 8 is a loading station, and the second workstation 9 is a punching and embossing station. The first workstation 8 and the second workstation 9 are arranged diagonally.

[0042] The positioning mechanism 3 further includes a positioning cylinder 304 for driving the positioning pin 302. The cylinder body of the positioning cylinder 304 is mounted on the positioning frame 301, and the piston rod of the positioning cylinder 304 is connected to the positioning pin 302. The positioning pin 302 is retractable under the action of the positioning cylinder 304. When loading a workpiece, the positioning pin 302 is extended to position the workpiece. After the workpiece punching and embossing process is completed, the positioning pin 302 is retracted to facilitate smooth workpiece discharge.

[0043] The positioning pin 302 is provided on the pin mounting plate 303 , and the piston rod of the positioning cylinder 304 is connected to the pin mounting plate 303 .

[0044] After the workpiece is punched and embossed, and before the turning mechanism 4 turns over, the positioning cylinder 304 is actuated to control the retraction of the positioning pin 302. The tray 402 of the turning mechanism 4 is then tilted to guide the workpiece so that it slides along the tray 402 onto the receiving mechanism 5. The retraction and expansion control of the positioning pin 302 not only ensures stable positioning of the workpiece but also prevents the positioning pin 302 from interfering with the workpiece during unloading.

[0045] A guardrail 101 is also provided in the middle of the rotary worktable 1. The first workstation 8 is located on one side of the guardrail 101, and the second workstation 9 is located on the other side of the guardrail 101. A worker loads a workpiece at the first workstation 8. After the rotary worktable 1 rotates 180 degrees, the workpiece is transferred to the second workstation 9 under the action of the rotary worktable 1. The second workstation 9 is an embossing processing station, where an embossing device such as an embossing gun is used to perform the embossing operation on the workpiece. The guardrail 101 can be used for manual loading and embossing of the workpiece, making the embossing and removal device safer and more reliable. In addition, the workpiece is loaded on one side of the guardrail 101 and removed from the other side. That is, the workpiece is loaded at the first workstation 8 and the workpiece is removed from the second workstation after embossing, avoiding confusion between the workpiece before and after embossing.

[0046] The machine also includes a turning mechanism 4 for discharging the workpiece after embossing, and a receiving mechanism 5 for receiving the workpiece. The receiving mechanism 5 is arranged on the discharge port side of the turning mechanism 4. After the workpiece embossing operation is completed, the clamping unit releases the workpiece, and the turning mechanism 4 is activated to release the workpiece from the clamping unit. The workpiece can be tilted and guided to the discharge port side, where it is received by the receiving mechanism 5 on the discharge port side, avoiding the unsafe situation of manually removing the embossed workpiece directly from the embossing position.

[0047] The flipping mechanism 4 includes a flipping bracket 401, a tray 402, a pair of connecting rod mechanisms arranged between the flipping bracket 401 and the tray 402, and a flipping cylinder 405. The tray 402 is provided with an avoidance slot 4021 on the inner side near the clamp unit, and a discharge stopper 4022 is provided on the tray 402 on both sides of the avoidance slot 4021; the connecting rod mechanism includes a first connecting rod 403 and a second connecting rod 404, the first connecting rod 403 and the second connecting rod 404 are arranged in parallel, the middle part of the first connecting rod 403 is hinged to the flipping bracket 401, one end of the first connecting rod 403 is hinged to the tray 402, and the other end is connected to the piston rod of the flipping cylinder 405; one end of the second connecting rod 404 is hinged to the tray 402, and the other end is hinged to the flipping bracket 401.

[0048] The tray 402 must be able to guide the embossed workpiece out of the material while avoiding interference with the fixture unit. Therefore, an avoidance slot 4021 is provided so that the discharge stopper 4022 on the inner side of the tray 402 can be located on the inner side of the workpiece of the fixture unit. When the tray 402 is tilted under the drive of the flip cylinder 405 and the connecting rod mechanism, the embossed workpiece can be guided to the discharge port side. The embossed workpiece can be placed on the material receiving mechanism 5 along the tray 402 which is higher inside and lower outside. After that, the workpiece can be taken out manually from the material receiving mechanism 5, and the material taking is safer and more reliable.

[0049] An intermediate connecting rod 408 is provided between the first connecting rods 403 of the pair of connecting rod mechanisms. A tilting cylinder 405 is mounted on the rotary table 1 via a cylinder bracket 409. The cylinder body of the tilting cylinder 405 is hingedly connected to the cylinder bracket 409. The piston rod of the tilting cylinder 405 is connected to the intermediate connecting rod 408. The tilting cylinder 405 drives the first connecting rod 403 via the intermediate connecting rod 408.

[0050] The flip bracket 401 includes a pair of frames connected by a first hinge shaft 406 and a second hinge shaft 407. The first connecting rod 403 is connected to the flip bracket 401 via the first hinge shaft 406, and the second connecting rod 404 is connected to the flip bracket 401 via the second hinge shaft 407. The hinge shaft is rotatably mounted on the flip bracket 401, and the connecting rod is connected to the hinge shaft. This not only facilitates connection but also further increases the support strength between the connecting rod mechanisms, thereby ensuring the stability of the tray 402 of the flip mechanism 4.

[0051] The tray 402 is provided with at least two pulley tracks 4023, each comprising a track seat and a plurality of pulleys rotatably mounted thereon. Glass wheels can be used for the pulleys, further reducing friction. Under the action of the tilting mechanism 4, the punched workpiece is discharged from the tilted tray 402. To further reduce friction between the workpiece and the support surface of the tray 402, pulley tracks 4023 can be provided on the support surface of the tray 402. The workpiece is supported on the pulleys, and rolling friction between the workpiece and the tray 402 further facilitates discharge.

[0052] The material receiving mechanism 5 includes an inclined section slide 501 and a horizontal section slide 502 connected at a lower position of the inclined section slide 501. The horizontal section slide 502 is provided with a protective plate on its periphery. The inclination angle of the inclined section slide 501 can be adjusted as needed to ensure that the workpiece can slide smoothly to the position of the horizontal section slide 502. The punched workpiece can be dropped onto the inclined section slide 501 of the material receiving mechanism 5 through the turning mechanism 4. Under the guidance of the inclined section slide 501, it enters the horizontal section slide 502. The horizontal section slide 502 is the workpiece removal position, where the processed workpiece can be manually removed.

[0053] The rotary table 1 is mounted on a bottom frame 6. At least one clamping mechanism 7 is provided between the rotary table 1 and the bottom frame 6 for positioning the adjusted rotary table 1. When the rotary table 1 rotates 180 degrees and the workpiece to be processed is transferred to the second station 9 for embossing, the clamping mechanism 7 can lock the rotary table 1 in place, further ensuring the stability of the workpiece during the embossing operation.

[0054] The clamping mechanism 7 includes a locking block 701, a fixed limiting block 702 for clamping the locking block 701, a movable limiting block 704, and a clamping cylinder 703 for driving the movable limiting block 704;

[0055] The locking block 701 is provided on the rotary worktable 1, the fixed limiting block 702 is provided on the bottom frame 6 via the column 705, the clamping cylinder 703 is provided on the bottom frame 6, the clamping cylinder 703 is provided with a clamping pressure arm 7031, and the movable limiting block 704 is provided on the clamping pressure arm 7031. The locking block 701 is provided at the bottom of the rotary worktable 1 via the connecting block 706. The clamping cylinder 703 is actuated to drive the clamping pressure arm 7031 to swing, and the limiting block provided on the clamping pressure arm 7031 can be swung toward the locking block 701 to limit it, thereby more stably positioning the rotary worktable 1 that has been rotated into position, or swung away from the locking block 701 to prevent the limiting block from interfering with the rotation of the rotary worktable 1. The rotary worktable 1 can rotate 180 degrees back and forth. The locking block 701 is arranged at the bottom of the rotary workbench 1. After the rotary workbench 1 rotates into position, one side of the locking block 701 contacts the fixed limit block 702, and the movable limit block 704 acts on the other side of the locking block 701 under the action of the clamping cylinder 703. The fixed limit block 702 and the movable limit block 704 cooperate to clamp the locking block 701, which can hook and position the rotary workbench 1 after it is rotated into position, thereby meeting the stability requirements of the punching operation.

[0056] After the workpiece is manually loaded at the first station 8, i.e., the loading position, if the workpiece is a stamping part, the rotary table 1 rotates 180°, and the workpiece is transferred to the second station 9, i.e., the embossing processing position. After the rotary table 1 is rotated into position, it can be clamped and fixed by the clamping mechanism 7. Then the robot carries a embossing device such as a embossing gun to emboss the workpiece. After the embossing operation is completed, the clamping unit is released, i.e., the positioning pin 302 retracts and the clamping mechanism is released. The tray 402 is slowly flipped under the action of the flip cylinder 405, and the workpiece is lifted up when the tray 402 is flipped. The workpiece is transferred from the clamping unit to the flipping position. On the tray 402 of the rotating mechanism 4, when the flip cylinder 405 flips the tray 402 at an angle to the horizontal plane, the tray 402 tilts higher inside and lower outside, and the workpiece slides along the pulley roller 4023 to the material receiving mechanism 5. The workpiece entering the material receiving mechanism 5 slides down along the inclined section slide 501 to the horizontal section slide 502 to stop, and then the operator can pick up the workpiece; after the workpiece slides to the material receiving mechanism 5, the clamping cylinder 703 is reset, and the rotary table 1 rotates 180 degrees in the opposite direction, and the next workpiece enters the second station 9 to wait for processing. At the same time, manual work can continue to load the workpiece at the first station 8. The rotary table 1 of the device rotates 180 degrees back and forth, with one side loading the workpiece and the other side punching the workpiece, which saves the operation time of the workstation and shortens the cycle time. It also avoids the confusion of the workpiece before punching and the workpiece after punching. The whole process of picking up the workpiece is stable and safe, which not only improves the punching cycle and meets the production requirements of high cycle for workpiece punching, but also has a simple structure, simplifies the structure of punching and picking up the workpiece, reduces costs, and is convenient for debugging and subsequent maintenance.
