Description

Technical Field

[0001] This utility model relates to the field of clamping technology, specifically to a composite profile handling device with a dual clamping mechanism. Background Technology

[0002] During the stacking and conveying of profiles, a special pad is placed between each layer to prevent direct contact between the profiles and subsequent surface scratches. This pad is specially designed with a cushioning material on its surface, which effectively isolates direct friction between the profiles and also prevents the pad itself from damaging the profiles.

[0003] Application CN119218730A discloses a sheet metal handling device and method. According to its description and accompanying drawings, the fixture mechanism includes a connecting frame fixedly connected to a second base, several elastic suction cup assemblies mounted on the connecting frame, and several pressing cylinders mounted on the connecting frame. The elastic suction cup assemblies adsorb the sheet metal, while the pressing cylinders press the sheet metal from above, causing slight deformation of the sheet metal, which, in conjunction with the elastic suction cup assemblies, separates the sheet metal.

[0004] However, the solution has certain limitations: 1. When using this solution to clamp and transport stacked profiles with pads, the clamping mechanism cannot indirectly lift the profiles placed on them by clamping and raising the pads. If the profiles are clamped directly, it will damage the surface of the profiles, causing inconvenience to the production process; 2. Since the pads are recycled when the profiles are transported to the designated location, and the profiles need to be clamped and transported to the designated area separately afterward, how to ensure that the subsequent gripping and conveying of the profiles can be facilitated while clamping the pads is also a problem that needs to be considered. Summary of the Invention

This device enables synchronous and adaptive gripping and handling of profiles and their pads, effectively solving the problems of low efficiency and inaccurate positioning in traditional methods. The beneficial effect is a significant improvement in the automation, accuracy, and adaptability of handling operations.

The third guide rail has a partition separating the plurality of third sliders in its middle. Each third slider has a clamping arm on its surface.

[0011] Preferably, each clamping arm includes a fixing part mounted on the third slider and a clamping part for clamping. The side wall of each clamping part is provided with an avoidance groove and the inside of the clamping part is provided with a semi-rectangular clamping groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This solution features a composite design where a first clamping component is used to clamp the profile and a second clamping component is used to clamp the pad. The second clamping component first clamps the pad and serves as a support base. Then, the profile supported on the pad is placed in the designated position. Finally, the first clamping component clamps the profile and places it in the next process, ultimately achieving integrated handling. This collaborative operation of the pad first and then the profile solves the problems of profile slippage, inaccurate positioning, and scratches on the profile surface during handling. 2. When the entire device descends to pick up the material, the guide plate contacts the pad before the clamping slot contacts it. The force of the continued descent is converted into a force that pushes the entire clamping base to slide upward along the second guide rail. This is a passive buffering and adaptive alignment process; it effectively prevents mechanical impact and damage caused by positional deviation. This floating stroke allows the bent part of the sheet metal to pass through the inside of the slot-shaped photoelectric sensor, thus providing key feedback information to the control system, enabling it to accurately determine: when the pad has correctly fallen into the clamping slot (the bent part of the sheet metal passes through the inside of the top slot-shaped photoelectric sensor), thereby activating the cylinder to clamp; and when the profile has been stably placed in the target position, and the clamping base resets under the weight of the profile (the sheet metal passes through the inside of the bottom slot-shaped photoelectric sensor), thereby safely releasing the pad. This method of deeply integrating mechanical floating buffering with photoelectric position detection and using it to control the clamping and release logic achieves intelligent and highly reliable operation of the entire handling process. 3. The design of the clearance groove on the clamping arm and the guide plate fixed on the guide support block not only provides a channel for the guide plate when clamping, but more importantly, when clamped, the guide plate passes into the clearance groove, forming lateral support for the clamping arm, which greatly enhances the rigidity and torsional resistance of the clamping structure and ensures the stability of the pad when the pad is supporting heavy profiles.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 and Figure 2 As shown, a composite profile handling device with a dual clamping mechanism includes a first clamping support body 1, on which a plurality of second clamping support bodies 2 are vertically arranged.

[0018] The first clamp support body 1 and the second clamp support body 2 are made of metal profiles, and the surface of the first clamp support body 1 is provided with a gripper fixing frame 13 connected to the end of the robotic arm or the lifting gantry frame. Several second clamp support bodies 2 are set on the gripper fixing frame 13. The robotic arm or the gantry frame with lifting and translation functions is a conventional standardized equipment in the field of automation equipment, and its principle and structure will not be described in detail here.

[0019] By adjusting the positions of the gripper fixing frame 13, the first clamp support body 1, and the second clamp support body 2 using a robotic arm or lifting gantry, the entire device can perform the handling operation after clamping the profile or pad.

[0020] In this embodiment, the first clamping support body 1 has first clamping components 3 for clamping the profile 10 on both sides, and each second clamping support body 2 has second clamping components 4 for clamping the pad 101 on both sides. The bottom sides of the first clamping support body 1 are provided with a first guide rail 11 and a first slider 12 slidably connected to the first guide rail 11. The bottom center of the first clamping support body 1 is also provided with a driving component 5 for driving the first slider 12 to slide relative to the first guide rail 11. Each first clamping component 3 is disposed on the first slider 12. During implementation, the drive component 5 can drive the first slider 12 to slide relative to the first guide rail 11; during the sliding process, the first slider 12 simultaneously causes the position of the first clamping component 3 to change; this setting is to make the first clamping component 3 slide more smoothly during the position change process; Furthermore, since the first clamping components 3 on both sides of the first clamping support body 1 can change their position relative to the first clamping support body 1 in the horizontal direction under the drive of the drive component 5, when facing profiles 10 of different lengths, these two first clamping components 3 can adjust their positions to adapt to the changed length of the profile 10, thereby further improving the gripping accuracy and working range.

[0021] Please continue to refer to the reference. Figure 3 and Figure 5 The drive assembly 5 includes a motor mounting base 51, a lead screw support 52, a dual-output shaft motor 53, a transmission lead screw 54, and a lead screw nut 55. The bottom of the first clamp support body 1 is provided with a motor mounting base 51 and several lead screw support 52s. The bottom of the motor mounting base 51 is provided with a dual-output shaft motor 53. Each output shaft end of the dual-output shaft motor 53 is connected to a transmission lead screw 54. Each transmission lead screw 54 is rotatably connected to the inside of the lead screw support 52. Each transmission lead screw 54 has a lead screw nut 55 on its surface. Each lead screw nut 55 is connected to the first clamping assembly 3.

[0022] During the process of driving the first slider 12: each output shaft of the dual output shaft motor 53 rotates, thereby driving the transmission screw 54 connected to the end to rotate simultaneously. During the rotation of the transmission screw 54, the thread on the surface of the transmission screw 54 interacts with the helical groove inside the screw nut 55, and is converted into linear motion through ball rolling friction, forcing the screw nut 55 to move axially. During the movement of the screw nut 55, the position of the first clamping assembly 3 changes simultaneously.

[0023] Please continue to refer to this. Figure 2 Each of the first clamping components 3 includes a clamping support plate 31, a nut fixing block 32, a rotary motor 33, and a pneumatic gripper 34. The bottom of each of the first sliders 12 is provided with a clamping support plate 31 in the shape of an inverted L. The top of each clamping support plate 31 is provided with a plurality of nut fixing blocks 32 for fixing the lead screw nut 55. A rotary motor 33 is provided on one side of the bottom of each clamping support plate 31. The rotating shaft of each rotary motor 33 is parallel to the first clamping support body 1, and the rotating shaft of the rotary motor 33 passes through the side wall of the clamping support plate 31 and is connected to a pneumatic gripper 34 for clamping the profile 10.

[0024] When the position of the lead screw nut 55 changes, the position of the entire first clamping assembly 3 changes through the nut fixing block 32; after the first clamping assembly 3 reaches the designated position, it needs to clamp the profile 10; the angle of the pneumatic gripper 34 changes through the rotating shaft of the rotary motor 33; whenever the pneumatic gripper 34 rotates to the designated angle, the pneumatic gripper 34 is used to clamp the profile.

[0025] Please continue to refer to this. Figure 2 and Figure 4 The second clamping assembly 4 includes a mounting plate 41, a second guide rail 42, a second slider 43, a clamping base 44, a third guide rail 45, a third slider 46, a partition 48, a cylinder element 49, and a clamping arm 47. Each second clamping support body 2 has a mounting plate 41 on both sides. Each mounting plate 41 has a second guide rail 42 and a second slider 43 slidably connected to the second guide rail 42 on its surface. Each second slider 43 has a clamping base 44 vertically mounted on it. The clamping base 44 has a third guide rail 45 parallel to the first clamping support body 1 and a plurality of third sliders 46 slidably connected to the third guide rail 45. The third guide rail 45 has a partition 48 in the middle that separates the plurality of third sliders 46. Each third slider 46 has a clamping arm 47 on its surface. The cylinder body and piston rod of the cylinder element 49 are respectively connected to the clamping arms 47 located on both sides of the partition 48.

[0026] like Figure 4In this configuration, when the length of the piston rod of the cylinder element 49 relative to the cylinder body changes, the piston rod pushes the connected clamping arm 47 and the third slider 46 below it to move along the third guide rail 45. Simultaneously, the cylinder element 49 applies an equal and opposite force to the other clamping arm 47 connected to the cylinder body and the third slider 46 below it, causing the third slider 46 to move in the opposite direction along the third guide rail 45. Therefore, the third sliders 46 on both sides of the partition 48 will slide simultaneously, but in opposite directions; during the sliding process of the two third sliders 46, the clamping arm 47 is simultaneously moved, enabling the clamping arm 47 to stably clamp the pad 101.

[0027] Each clamping arm 47 includes a fixing part 471 mounted on the second slider 43 and a clamping part 472 for clamping. Each clamping part 472 has a clearance groove 473 on its side wall and a semi-rectangular clamping groove 474 inside. Each clamping base 44 also has a guide support block 6 at its bottom. Each guide support block 6 has a guide plate 61 inside. Both ends of each guide plate 61 pass through the interior of the clearance groove 473.

[0028] During the clamping process of the adjacent clamping arms 47 under the drive of the cylinder element 49, the profile will gradually be stuck inside the clamping groove 474; when the adjacent clamping arms 47 are completely closed (in contact with each other), the inner wall of the clearance groove 473 of the pad 101 plus the guide plate 61 completes the clamping and limiting of each side wall of the pad 101, and the pad 101 is stably clamped inside the clamping groove 474. To enhance the service life of the clamping arm 47, the clearance groove 473 of the clamping arm 47 passes through the surface of the guide plate 61 during the clamping process. The guide plate 61 can also support and guide the clamping arm 47, and has better load-bearing capacity during the stress process.

[0029] Each clamping base 44 is also provided with several sheet metal parts 7 with the same horizontal plane on the side near the mounting plate 41. The surface of the mounting plate 41 is provided with several slotted photoelectric sensors 8 with different heights relative to the second clamping support body 2. When the height of the clamping base 44 relative to the mounting plate 41 changes, the bent part of the sheet metal part 7 can pass through the inside of the slotted photoelectric sensor 8. The second guide rail 42 is also provided with a linear guide limit block 9 for limiting the sliding distance of the second slider 43 on the second guide rail 42. Before each cylinder element 49 controls the clamping arm 47 to clamp the pad 101, it needs to determine whether the inside of the clamping groove 474 of the entire second clamping assembly 4 is against the surface of the pad 101. Therefore, during the process of the robotic arm or lifting gantry controlling the height of the entire second clamping support body 2 to change, as the height changes continuously, the side of the guide plate 61 near the clamping groove 474 will first be pushed by the pad 101. This push force borne by the guide plate 61 will be transmitted to the entire clamping base 44, causing the clamping base 44 and the second slider 43 to slide relative to the second guide rail 42. Please refer to the reference. Figure 6 During the sliding process, each clamping base 44 will simultaneously drive the sheet metal part 7 to slide; after the curved part of the sheet metal part 7 passes through the interior of the bottom slotted photoelectric sensor 8 and the top slotted photoelectric sensor 8 in sequence, until it leaves the interior of the bottom slotted photoelectric sensor 8, the second slider 43 is blocked by the top linear guide limit block 9; therefore, at this time the entire pad 101 and the clamping groove 474 completely fall into the clamping arm 47 can then be activated to control the clamping arm 47 to clamp the pad 101. Similarly, after clamping is completed, as the height of the entire second clamping support body 2 changes again, several clamped pads 101 will lift the profile 10 on the surface of the pads 101 away from the initial position; at this time, the gravity generated by the profile 10 on the surface of the pads 101 will cause the clamping base 44 and the second slider 43 to slide relative to the second guide rail 42. Similarly, when the bent part of the sheet metal part 7 passes through the interior of the slotted photoelectric sensor 8 at the bottom again, until it leaves the interior of the slotted photoelectric sensor 8 at the top, it means that the entire clamping base 44 and the surface components have completed the initial reset. When the bent part of the sheet metal part 7 passes through the interior of the slotted photoelectric sensor 8 at the top again, it means that the profile supported on the pad 101 has been placed in the designated position. At this time, the cylinder element 49 can control the clamping arm 47 to end the clamping of the pad 101, and the pad 101 will fall down to wait for recycling.

[0030] Working principle and usage of this utility model: The second clamping assembly 4 changes position under the drive of the robotic arm or the lifting gantry, so that the guide plate 61 at the bottom of the second clamping assembly 4 will first contact the surface of the pad 101.

[0031] As it continues to descend, the pad 101 will exert an upward thrust on the guide plate 61. This force is transmitted to the clamping base 44 through the guide support block 6, forcing the clamping base 44 and the second slider 43 to slide upward along the second guide rail 42.

[0032] The sheet metal part 7, fixed to the clamping base 44, moves upward accordingly. When the bent portion of the sheet metal part 7 passes through the slotted photoelectric sensors 8 at different heights on the mounting plate 41, the sensors emit signals. This process is used to accurately determine whether the pad 101 has fully entered the clamping slot 474 and whether the device has completed the pick-up or placement action. The linear guide limit block 9 is used to limit the sliding stroke of the second slider 43 to prevent overshoot.

[0033] The piston rod of cylinder element 49 retracts. The cylinder body and piston rod of cylinder element 49 are respectively connected to the clamping arms 47 on both sides of the partition 48. When the cylinder is actuated, it pushes the two clamping arms 47, along their respective third sliders 46, to move towards each other along the third guide rail 45.

[0034] When the two clamping arms 47 move toward each other, the half-rectangular clamping grooves 474 inside them merge into a complete rectangular space, tightly enclosing the edge of the pad 101. At the same time, the clearance grooves 473 on the side walls of the clamping arms 47 slide along the guide plate 61. The guide plate 61 not only serves as a guide but also provides support for the clamping action, enhancing the rigidity and stability of the clamping.

[0035] Next, the second clamping assembly 4 is repositioned under the drive of the robotic arm or the lifting gantry frame, and the profile on the surface of the pad 101 is placed on the surface of the conveyor belt of several parallel conveyors. The conveyor belts of several conveyors support a portion of the profile 10, and the clamped pad 101 passes through the gap between several conveyors to wait for the pad 101 to be recovered.

[0036] Next, the dual-output shaft motor 53 in the drive assembly 5 starts, driving the transmission screws 54 at both ends to rotate synchronously. The rotational motion of the transmission screws 54 is converted into linear motion through the screw nut 55. The screw nut 55 is connected to the clamping support plate 31 of the first clamping assembly 3 through the nut fixing block 32.

[0037] The linear motion of the lead screw nut 55 drives the entire first clamping assembly 3 to slide along the first guide rail 11 via the first slider 12. By controlling the direction and angle of rotation of the dual output shaft motor 53, the distance between the first clamping assemblies 3 on both sides of the device can be precisely controlled to accommodate profiles 10 of different lengths.

[0038] For profiles requiring angle adjustment, the rotary motor 33 starts, driving the pneumatic gripper 34 on its shaft to rotate to the preset angle. After the angle is adjusted, the pneumatic gripper 34 moves to firmly clamp the profile 10; finally, the gripped profile 10 is placed in the designated position.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
