[0025] This utility model provides a profile feeding and gripping device, which solves the problems of unstable clamping and movement of profiles in existing equipment, so as to achieve a more reliable and efficient feeding process.

[0026] Please see Figure 1 This utility model discloses a profile material grabbing device, mainly comprising a frame 1, a scissor-type lifting mechanism 2, and a grabbing mechanism 3. The frame 1 includes uprights and crossbeams 11 disposed on the upper part of the uprights; in a specific embodiment, the uprights are four vertically arranged quadrilaterals with their four vertices distributed, and upright beams are provided on the two uprights on the left and two uprights on the right. Two crossbeams 11, one in front and one behind, are arranged transversely between the two upright beams on the left and right sides. Optionally, such as... Figure 5 As shown, the columns and column beams are also connected by diagonal braces 12 to increase structural strength. The frame 1 is, for example, welded from steel profiles.

[0027] The scissor lift mechanism 2 is an existing structure, and its specific structure will not be described in detail here. It mainly includes an upper part that is generally plate-shaped, a lower part that is generally plate-shaped, and a scissor structure located between the two. The scissor structure has, for example, a hydraulic cylinder for driving, thereby realizing the change of the height distance between the upper and lower parts of the scissor lift mechanism 2, that is, lifting.

[0028] The crossbeam 11 is connected to the upper part of the scissor lift mechanism 2, for example, by welding. The lower part of the scissor lift mechanism 2 is connected to the gripping mechanism 3 so that the gripping mechanism 3 can be raised and lowered. In this design, all or most of the scissor lift mechanism 2 is located below the crossbeam 11. When the scissor structure is extended and retracted, it is within the range below the crossbeam 11 of the frame 1, so there is no problem of change in total height. Furthermore, when the gripping mechanism 3 is in the highest position, the overall height of the scissor structure is at its minimum, so the overall center of gravity is low, which facilitates the stable operation of the equipment.

[0029] Multiple lifting guide rods 21 are fixedly installed on the upper part of the scissor lift mechanism 2. The lifting guide rods 21 extend downward from the upper part of the scissor lift mechanism 2, and the multiple lifting guide rods 21 are parallel to each other, for example, all of them are vertically arranged. A guide rod guide seat 22 is fixedly installed on the lower part of the scissor lift mechanism 2, and the lifting guide rods 21 are slidably connected to the guide rod guide seat 22. In this solution, the lifting guide rods 21 improve the stability of the lifting process and avoid swaying. In addition, the lifting guide rods 21 are all or most of the way below the crossbeam 11, and their positions remain fixed during the lifting process, which also has the beneficial effect of a low center of gravity and further stability. Of course, the length of the lifting guide rods 21 matches the scissor lift mechanism 2, and the lifting guide rods 21 and guide rod guide seats 22 will not separate after the scissor structure is deployed; and the length of the lifting guide rods 21 is designed to be as short as possible so as not to affect the operation of the gripping mechanism 3, and the lifting guide rods 21 will not contact the profile when handling the profile.

[0030] Please also refer to Figures 2 to 4 The gripping mechanism 3 includes a gripping bracket 31, which is connected to the lower part of the scissor lift mechanism 2. The gripping bracket 31 is, for example, a horizontally arranged plate, specifically a welded frame structure. Both sides of the gripping bracket 31 are slidably connected to a loading claw arm 331 via a loading claw transverse guide rail assembly 32. More specifically, both sides of the gripping bracket 31 have a horizontal bar extending from them, and a guide rail for the loading claw transverse guide rail assembly 32 is provided on the horizontal bar. A matching slider is slidably connected to the guide rail, and the slider is directly or indirectly fixedly connected to the loading claw arm 331. The lower end of the loading claw arm 331 has a loading claw gripping head 332, which allows the left and right loading claw gripping heads 332 to jointly support and transport the profile. The gripping mechanism 3 also includes a lateral movement control transmission mechanism for controlling the lateral movement of the loading claw boom 331, thereby enabling the increase and decrease of the distance between the left and right loading claw gripping heads 332.

[0031] More specifically, on each of the left and right sides of the gripping bracket 31, there are multiple loading claw arms 331, for example, four on each side. These multiple loading claw arms 331 are arranged in a row relatively aligned in the front-to-back direction, and are fixedly connected to each other via synchronous connecting rods 333. Figure 2In the illustrated embodiment, a slider connecting bracket is provided on the synchronous connecting rod 333, forming a ring that fits onto the crossbar of the aforementioned gripping bracket 31 and is fixedly connected to the slider of the loading claw transverse guide rail assembly 32. This allows the loading claw arm 331 and the synchronous connecting rod 333, as a connected whole, to be slidably connected to the gripping bracket 31. It can be understood that the distribution range of the multiple loading claw arms 331, the length range of the synchronous connecting rod 333, and the length range of the gripping bracket 31 are basically consistent. Each loading claw arm 331 corresponds to a crossbar and a loading claw transverse guide rail assembly 32, thereby enabling the multiple loading claw arms 331 in each row to move synchronously and without deviation in the front-back direction.

[0032] A preferred lateral movement control transmission mechanism includes a drive shaft 341, which is rotatably connected to the lower part of the scissor lift mechanism 2 or the gripping bracket 31 (e.g., mounted on the side of the lower part of the scissor lift mechanism 2 via a bearing bracket). An eccentric shaft 342 is mounted on the drive shaft 341. A drive motor 343 is drivenly connected to the drive shaft 341, for example... Figure 3 As shown, the drive motor 343 is fixedly connected to the lower part of the scissor lift mechanism 2 or the gripping bracket 31 via the torsion bracket 348. The drive motor 343 is located in the middle of the transmission shaft 341. The output end of the drive motor 343 has a gearbox, which is connected to the transmission shaft 341 and can drive the transmission shaft 341 to rotate forward and reverse.

[0033] On each of the left and right sides of the gripping bracket 31, a drive shaft 341 arranged in the front-to-back direction is rotatably connected. A connecting plate 344 is fixedly connected to the synchronous connecting rod 333 on each side. The connecting plate 344 has a strip hole 345, and the eccentric shaft 342 is located in the strip hole 345, forming a cam pair. Specifically, for example, the connecting plate 344 is perpendicular to the synchronous connecting rod 333, and the strip hole 345 is offset from the synchronous connecting rod 333 and is vertical. Thus, under the limiting action of the cam pair and the loading claw transverse guide rail assembly 32, when the drive shaft 341 rotates, the eccentric shaft 342 makes a circular motion and moves up and down in the strip hole 345, while pushing / pulling the synchronous connecting rod 333 to move laterally. Preferably, an eccentric shaft 342 is respectively provided at both ends of a drive shaft 341, and two connecting plates 344 are provided on each synchronous connecting rod 333, so as to evenly push the two ends of the synchronous connecting rod 333.

[0034] Please also refer to Figure 4 , Figure 6 , Figure 7In a preferred embodiment, the feeding claw gripper head 332 is plate-shaped, and the feeding claw gripper heads 332 on both sides of the gripping bracket 31 are arranged opposite each other, facing inwards, and horizontally. The lower end of the feeding claw arm 331 is hinged to the feeding claw gripper head 332, for example, by a pin. The hinge point between the feeding claw gripper head 332 and the feeding claw arm 331 is located on the outer side of the feeding claw gripper head 332, and the lower end of the feeding claw arm 331 has clearance space on the inner side of the hinge point, and the lower end of the feeding claw arm 331 has a horizontal lower end face on the outer side of the hinge point. Under natural conditions, under the action of gravity, the feeding claw gripper head 332 is horizontal and the outer end of the feeding claw gripper head 332 is in contact with the horizontal lower end surface of the outer side of the feeding claw arm 331. When the feeding claw gripper head 332 descends, the inner end encounters an obstacle and can rotate. The inner end of the feeding claw gripper head 332 is lifted and continues to descend past the obstacle before the feeding claw gripper head 332 falls freely.

[0035] Please see Figure 6 In some embodiments, during operation, the unloaded loading claw boom 331 first moves outward and descends to position 3' in the figure, then moves inward to position 3'', and then moves upward, thus lifting the profile support rod 7 via the loading claw gripping head 332. In the preferred embodiment using the hinged loading claw gripping head 332 described above, the unloaded loading claw boom 331 can directly descend vertically to position 3'', and the loading claw gripping head 332 can automatically pass over the profile support rod 7 by rotation, thus making the operation simpler and more efficient.

[0036] For more details, please refer to Figure 1 , Figure 5 , Figure 6 The upper and lower parts of the scissor lift mechanism 2 are both horizontal square frame structures, for example, welded from steel. A guide rod fixing beam 23 is fixedly installed horizontally above the upper square frame structure of the scissor lift mechanism 2, and the lifting guide rod 21 is fixedly connected to the guide rod fixing beam 23. Similarly, a guide rod guide seat 22 is fixedly installed horizontally above the lower square frame structure of the scissor lift mechanism 2. This specific arrangement is more conducive to the fixation and stress stability of the lifting guide rod 21.

[0037] Furthermore, there are four lifting guide rods 21, located at the four corners of the square frame structure near the scissor lift mechanism 2, thereby further ensuring the smoothness of lifting. More specifically, the guide rod guide seat 22 is provided with multiple guide holes, and the lifting guide rods 21 are inserted into the guide holes one by one. In at least one guide hole (for example, in two guide holes), a guide rod lifting linear bearing is also provided, and the lifting guide rods 21 are slidably connected to the guide rod lifting linear bearing.

[0038] Please see Figure 3In a preferred embodiment, the lateral movement control transmission mechanism includes a sensor (not shown in the figure). A sensing plate 346 is fixedly mounted on the synchronous connecting rod 333, and a switch bracket 347 is fixedly mounted on the lower part of the scissor lift mechanism 2 or on the gripping bracket 31. The sensor is mounted on one of the switch bracket 347 and the sensing plate 346 and faces the other of the switch bracket 347 and the sensing plate 346. The sensor is connected to the control system or the drive motor 343, for example, so that when the left and right loading claw arms 331 move inward to the required distance corresponding to the length of the profile support rod 7, the sensor on the switch bracket 347 can just detect that the sensing plate 346 has entered its sensing range, thereby sending a signal to the drive motor 343 to stop the drive motor 343. Preferably, the switch bracket 347 has a strip hole, so the sensor installation position can be adjusted to accommodate different lengths of the profile support rod 7.

[0039] As a more specific supplement, a conveyor 5 for conveying the material frame 4 is installed on the ground below the crossbeam 11 of the frame 1. The length direction of the conveyor 5 is the front-to-back direction. Multiple vertical railings are distributed on the sides of the material frame 4, and multiple 332 loading claw grippers are located in the gaps between the railings. Profiles 6 are stacked in layers on the material frame 4, with the length direction of the profiles 6 also being the front-to-back direction. Each layer of profiles 6 is separated by several horizontally arranged profile support rods 7, the ends of which extend beyond the sides of the material frame 4 for gripping by the gripping mechanism. Furthermore, the parallelism of each linear guide rail in this device is, for example, 1 mm / m. After the profile is gripped, it may be necessary to continue moving the profile horizontally. This process can be achieved through the loading claw transverse guide rail assembly 32, or by other movable beam connection structures, such as the gripping bracket 31 being movable on the scissor lift mechanism 2, or the scissor lift mechanism 2 being movable on the beam 11, or the beam 11 being movable on the column beam of the frame 1, etc. It is understood that this document only details the key improvements of this solution; the remaining specific technical contents can be selected by using existing technology or adopting other feasible implementation methods.

[0040] In summary, the profile feeding and gripping device of this utility model adopts a scissor-type lifting mechanism and is equipped with a lifting guide rod. The guide rod positioning ensures the stability of the lifting process of the gripping mechanism. The gripping mechanism provides a transverse guide rail assembly to realize translation and complete the gripping and releasing actions. The spacing of the feeding claw gripping heads can adapt to different material frame loading situations, and the translation process of the feeding claw gripping heads is stable. This ensures the stability, efficiency, flexibility, and jam-free operation of the profile feeding and dispensing process, and helps to ensure the surface quality of the profile.
