Description

Technical Field

[0001] This utility model relates to the technical field of grafting auxiliary processing equipment, specifically to a cutting and clamping device that uses a cylinder and a pneumatic gripper in synergistic operation. Background Technology

[0002] Grafting clips are consumables used to fix the scion and rootstock during the grafting process. Their processing precision and clamp supply efficiency directly determine the quality and production capacity of the grafting operation. In traditional small-scale production, grafting clip processing relies on manual labor to cut long, continuous clip blanks, manually open them, and supply the clips one by one.

[0003] In practice, workers need to use a utility knife or a simple hacksaw to judge the length based on experience and cut long strips of grafting clip blanks. After cutting, they need to use tweezers or homemade metal clips to open the closed clamp arms of the clip body to keep it open. Then, they need to place the open grafting clips one by one into the positioning slots of the grafting station.

[0004] However, the above-mentioned processing mode of grafting clips is not only labor-intensive, but also prone to defects such as deviation in the length of the clip embryo and rough edges due to uneven cutting force. This leads to deviation in the placement of the clips during subsequent supply, resulting in the grafted seedlings not being firmly fixed, and even directly affecting the survival rate of the grafted seedlings. It is difficult to meet the precision and efficiency requirements of large-scale production lines. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting and clamping device for the processing of grafting clips, so as to improve processing efficiency and accuracy, and to meet the requirements of large-scale production lines for grafting clip supply efficiency and processing accuracy.

[0006] To achieve the above objectives, this utility model proposes a cutting and clamping device for coordinated operation of cylinder and pneumatic gripper, comprising a conveying component, a cutting component, and an upper clamping component arranged sequentially along the conveying direction of the strip-shaped clamp blank. The conveying component includes a conveying cylinder and a clamping gripper for clamping the strip-shaped clamp blank. The clamping gripper is installed at the piston rod end of the conveying cylinder. The conveying component is configured to drive the clamping gripper to reciprocate along the conveying direction of the strip-shaped clamp blank using the conveying cylinder, and to use the clamping gripper to jointly clamp the strip-shaped clamp blank and convey the length of a single grafting clamp to the cutting component. The cutting component is located on one side of the conveying component and is used to cut the conveyed strip-shaped clamp blank to form a grafting clamp; The upper clamping component includes a telescopic cylinder and an opening gripper. The opening gripper is installed at the piston rod end of the telescopic cylinder. The upper clamping component is configured to use the telescopic cylinder to drive the opening gripper to receive the grafting clamp, and to use the opening gripper to cooperate in opening the grafting clamp to form a continuous clamping supply to the grafting station.

[0007] The coordinated combination of the conveying cylinder and the clamping gripper, as well as the telescopic cylinder and the expanding gripper, enables precise feeding of the strip-shaped clamp blank and precise clamping of the grafting clamp, respectively. Furthermore, the components are arranged in an orderly manner along the clamp blank conveying direction, forming a continuous operation link. This can stably adapt to the continuous production needs of the grafting station and avoid the stagnation of the grafting process due to the interruption of clamping supply.

[0008] Preferably, the upper clamping component is located below the cutting component, and the upper clamping component is configured to use a telescopic cylinder to drive the pneumatic gripper to move from bottom to top to support and receive the grafting clamp.

[0009] Preferably, the cutting component includes a cutting cylinder and a cutting blade assembly. The cutting cylinder is arranged perpendicular to the conveying direction of the strip-shaped blank, and the cutting blade assembly is installed at the piston rod end of the cutting cylinder. The cutting component is configured to use the cutting cylinder to drive the cutting blade assembly to make a transverse cut on the strip-shaped blank.

[0010] Preferably, the conveying component, the cutting component, and the upper clamping component are all mounted on the worktable.

[0011] Preferably, a guide assembly is also provided on the workbench. The guide assembly includes a guide roller and a guide seat. The guide seat is arranged parallel to the conveying component and a conveying channel is provided on the guide seat. The conveying channel is arranged along the conveying direction of the strip-shaped blank, and the guide roller is arranged on the inlet side of the conveying channel.

[0012] Preferably, the cutting assembly includes a blade holder and a blade, with the blade holder mounted on the piston rod end of the cutting cylinder and the blade detachably mounted on the blade holder.

[0013] Preferably, the end of the gripper is provided with a pair of gripping arms, and the gripping arms are provided with grooves for matching the strip-shaped clamping blank.

[0014] Preferably, the stroke of the delivery cylinder is 20mm-50mm.

[0015] Compared with existing technologies, the cylinder-gripper collaborative cutting and clamping device provided by this utility model has the following substantial features and advancements: This cylinder-gripper collaborative cutting and clamping device seamlessly connects the conveying, cutting, and clamping processes of strip-shaped clamp blanks through the sequential cooperation of a conveying component, a cutting component, and an upper clamping component. The entire process relies on the collaborative drive of cylinders and grippers, requiring no manual intervention. This completely solves the intermittent problem of traditional manual operation, enabling continuous production and clamping of grafting clamps, significantly improving overall work efficiency. The conveying cylinder drives the gripper to precisely convey the strip-shaped clamp blanks according to the length of each grafting clamp, avoiding conveying deviations. The cutting component cuts based on the precisely conveyed clamp blanks, ensuring uniform dimensions for each grafting clamp. The upper clamping component uses a telescopic cylinder to precisely position and open the gripper to receive the grafting clamp, further ensuring the accuracy of the clamping position. This improves product consistency throughout the entire process from production to clamping, adapting to the requirements of large-scale production lines for clamping efficiency and processing precision.

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Currently, the processing method for grafting clips is not only labor-intensive, but also prone to defects such as length deviations and burrs due to uneven manual cutting force. This leads to inaccurate placement of the clips during subsequent feeding, resulting in unstable grafting and even directly affecting the survival rate of the grafted seedlings. This makes it difficult to meet the precision and efficiency requirements of large-scale production lines. This utility model proposes a cutting and feeding device using a cylinder and pneumatic gripper working in tandem, aiming to improve processing efficiency and precision in the grafting clip manufacturing process, thus meeting the requirements of large-scale production lines for grafting clip feeding efficiency and processing precision.

[0023] The cutting and clamping device with cylinder and gripper coordination proposed in this embodiment of the utility model seamlessly connects the processes of conveying, cutting and clamping strip blanks through the sequential cooperation of the conveying component, the cutting component and the clamping component. The entire process relies on the coordinated drive of cylinder and gripper, eliminating the need for manual conveying, cutting or placing of grafting clamps. On the one hand, it avoids problems such as dimensional deviation and clamping misalignment caused by fatigue and experience differences in manual operation, thereby improving the stability of operation and processing accuracy. On the other hand, it reduces labor costs and lowers the production and operation costs of enterprises.

[0024] like Figure 1 As shown, a cutting and clamping device for coordinated operation of cylinder and pneumatic gripper includes a conveying component 1, a cutting component 2, and an upper clamping component 3 arranged sequentially along the conveying direction of the strip-shaped clamp blank. Figure 1 The arrows shown indicate the conveying direction of the strip-shaped clamp blanks.

[0025] like Figure 2 As shown, the conveying component 1 includes a conveying cylinder 11 and a clamping gripper 12 for holding the strip-shaped clamp blank. The clamping gripper 12 is mounted on the piston rod end of the conveying cylinder 11. The conveying component 1 is configured to drive the clamping gripper 12 to reciprocate along the conveying direction of the strip-shaped clamp blank using the conveying cylinder 11, and to use the clamping gripper 12 to cooperate in clamping the strip-shaped clamp blank and conveying the length of a single grafting clamp to the cutting component 2.

[0026] like Figure 1 As shown, the cutting component 2 is located on one side of the conveying component 1 and is used to cut the conveyed strip-shaped clamp blank to form a grafting clamp.

[0027] like Figure 2 As shown, the upper clamping component 3 includes a telescopic cylinder 31 and an opening gripper 32. The opening gripper 32 is mounted on the piston rod end of the telescopic cylinder 31. The upper clamping component 3 is configured to use the telescopic cylinder 31 to drive the opening gripper 32 to receive the grafting clamp, and to use the opening gripper 32 to cooperate in opening the grafting clamp to form a continuous clamping supply to the grafting station.

[0028] In this process, the clamping gripper 12 of the conveying component 1 first performs a closing action, clamping the ends of the strip-shaped blank from both sides to ensure that there is no relative sliding between the blank and the gripper. After the clamping gripper 12 clamps the blank, the piston rod of the conveying cylinder 11 extends outward according to a preset stroke, driving the clamping gripper 12 to move linearly along the conveying direction with the strip-shaped blank until the section of the blank to be cut is pushed under the cutter of the cutting component 2, and the blank is conveyed into place.

[0029] After the clamping blank is delivered to the position, the clamping gripper 12 opens to release the clamping blank. Then, the piston rod of the conveying cylinder 11 retracts, driving the clamping gripper 12 back to the initial clamping position, ready for the next clamping blank grabbing and conveying. The clamping blank is used to send the previously cut grafting clamp to the upper clamping component 3, completing a single clamping blank conveying cycle.

[0030] For example, the stroke of the conveying cylinder 11 is 20mm-50mm. The length of common grafting clips is usually in the range of 20mm-50mm. By setting the stroke of the conveying cylinder 11 to this range, the stroke parameters can be adjusted to directly adapt to the needs of grafting clips of different lengths without replacing the cylinder or modifying the mechanical structure. The single conveying length can be set only through the control system, which greatly improves the compatibility of the device with different products and reduces the adjustment costs during production changeover.

[0031] To further optimize the spatial layout of the device, such as Figure 2 As shown, the upper clamping component 3 is located below the cutting component 2. The upper clamping component 3 is configured to use a telescopic cylinder 31 to drive the pneumatic gripper 32 to move from bottom to top to support and receive the grafting clamp.

[0032] Therefore, the upper clamping component 3 adopts a structural design located below the cutting component 2 and supported from bottom to top. By utilizing the longitudinal space below the cutting component 2, the core components are arranged in a three-dimensional manner along the longitudinal and transverse directions. While ensuring the continuity of the entire process of conveying, cutting and clamping, the overall compactness of the equipment structure is greatly improved.

[0033] Compared to lateral or top-down gripping methods, when the pneumatic gripper 32 lifts and receives the grafting clip from bottom to top, the weight of the grafting clip can be balanced against the lifting force of the pneumatic gripper 32. This ensures that the grafting clip can be stably placed within the gripping area of ​​the pneumatic gripper 32, avoiding the grafting clip's displacement or falling due to lateral pushing, or the possible misalignment problems that may occur when gripping from top to bottom. At the same time, the lifting method reduces rigid collisions between the pneumatic gripper 32 and the grafting clip, reducing the risk of deformation and breakage of the grafting clip due to uneven force, effectively reducing material loss and improving the yield rate.

[0034] like Figure 2As shown, the cutting component 2 includes a cutting cylinder 21 and a cutter assembly 22. The cutting cylinder 21 is arranged perpendicular to the conveying direction of the strip-shaped blank. The cutter assembly 22 is mounted on the piston rod end of the cutting cylinder 21. The cutting component 2 is configured to use the cutting cylinder 21 to drive the cutter assembly 22 to make a transverse cut on the strip-shaped blank.

[0035] Therefore, the cutting path of the cutter assembly 22 has no angular deviation from the blank conveying direction, and can accurately align with the preset cutting line, avoiding problems such as slanted cuts and burrs caused by tilted cutting direction. At the same time, the linear motion stroke driven by the cylinder is stable and controllable. The cutting depth and lateral movement distance of the cutter assembly 22 are completely consistent each time, ensuring that the length of each grafting clamp and the flatness of the cut are uniform. This ensures high precision and consistency of product dimensions from the core process, reducing defective products caused by cutting deviations.

[0036] like Figure 2 and Figure 3 As shown, the cutting assembly 22 includes a blade holder 221 and a blade 222. The blade holder 221 is mounted on the piston rod end of the cutting cylinder 21, and the blade 222 is detachably mounted on the blade holder 221. After prolonged use, the blade 222 will wear down, leading to a decrease in cutting accuracy. The detachable design allows for quick replacement of the blade 222 without disassembling the entire connection between the blade holder 221 and the cutting cylinder 21 when the blade 222 is worn or damaged. Simply loosen the screws, clips, and other fasteners securing the blade 222.

[0037] To further improve the overall stability of the device, such as Figure 2 As shown, the conveying component 1, the cutting component 2, and the upper clamping component 3 are all mounted on the worktable 4. The worktable 4 provides a uniform mounting plane and height reference for all components, and the height of the worktable 4 can be designed according to the operator's working habits.

[0038] like Figure 2 and Figure 3 As shown, a guide assembly 5 is also provided on the worktable 4. The guide assembly 5 includes a guide clamp roller 51 and a guide seat 52. The guide seat 52 is arranged parallel to the conveying component 1. A conveying channel 53 is provided on the guide seat 52. The conveying channel 53 is arranged along the conveying direction of the strip-shaped blank. The guide clamp roller 51 is arranged on the inlet side of the conveying channel 53.

[0039] Therefore, the conveying channel 53 on the guide seat 52 is arranged along the conveying direction of the strip-shaped clamp blank, and its inner diameter is precisely matched with the cross-sectional size of the clamp blank. It can form a wrapping guide from both sides and the top and bottom directions of the clamp blank, avoiding the problem of the clamp blank shifting left and right or warping up and down due to insufficient rigidity or external interference during the conveying process.

[0040] Meanwhile, the guide roller 51 located at the entrance side of the conveying channel 53 can pre-correct the blank before it enters the channel. Through the symmetrical clamping force of the roller, the blank, which may be tilted or deviated, is adjusted to an alignment with the conveying channel 53, ensuring that the blank can smoothly enter the channel and be conveyed along the preset trajectory.

[0041] like Figure 4 As shown, the end of the gripper 12 is provided with a pair of gripping arms 13. The gripping arms 13 are provided with grooves 14 for matching the strip-shaped clamp blank. The sidewalls of the grooves 14 limit the sides of the clamp blank, preventing it from sliding left and right or moving up and down during the reciprocating motion driven by the conveying cylinder 11. The groove 14 design significantly improves the fit between the clamp blank and the gripping arms 13. Even under the inertia of the cylinder starting and stopping, the clamp blank can be stably fixed in the groove 14, ensuring that the conveying cylinder 11 accurately pushes the clamp according to the length of a single grafting clamp. This ensures the positioning accuracy of subsequent cutting and clamping processes from the source of the conveying process, reducing conveying errors caused by clamp blank offset.

[0042] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
