Description

Technical Field

[0001] This invention relates to the field of automatic outer tube assembly apparatus, and in particular to an automatic outer tube assembly apparatus for a cutting component on a stapler. Background Technology

[0002] As a crucial instrument in minimally invasive surgery, the stapler requires a high degree of precision and reliability in its production process. The assembly of the outer sheath in the cutting assembly is the final step, and the current common process is as follows: First, the outer sheath is manually loaded onto the designated station of the equipment. Then, the operator places the cutting assembly mounting part at the assembly station, and the equipment assembles the outer sheath and the cutting assembly mounting part. Finally, the assembled cutting assembly is manually removed. This process is semi-automated, and the assembly of the cutting assembly involves multiple steps, each requiring manual intervention. This not only significantly increases the labor intensity of the operators but also easily leads to fatigue due to prolonged repetitive work, thereby increasing the risk of operational errors and ultimately adversely affecting the consistency and quality stability of the product. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the installation of the outer tube and the cutting component of the existing stapler is carried out by semi-automatic assembly, which relies on manual labor, significantly increases the labor intensity of the operators, and is prone to fatigue due to long-term repetitive work, thereby increasing the risk of misoperation and ultimately adversely affecting the consistency and quality stability of the product. The present invention provides an automatic assembly device for the outer tube of the cutting component on the stapler.

[0004] The technical solution adopted by this invention to solve its technical problem is: an automatic assembly device for the outer sheath of a cutting component on a stapler, comprising an assembly platform, and further comprising:

[0005] A vehicle used to load assembled cutting components;

[0006] A conveying mechanism, which is set on the assembly platform, is used to transport the carrier from the previous process to the workstation;

[0007] The first hopper mechanism is located on the assembly platform and is used to store the outer casing tube;

[0008] A rotation detection mechanism is set on the assembly platform and is used to clamp the outer sleeve and detect its rotational attitude.

[0009] The first conveying mechanism is set on the assembly platform and located between the first hopper mechanism and the rotary detection mechanism, and is used to transfer the outer sleeve in the first hopper mechanism to the rotary detection mechanism.

[0010] A cutting component positioning mechanism is set on the assembly platform and is used to position the cutting components to be assembled;

[0011] An assembly mechanism is set on the assembly platform and located between the rotary detection mechanism and the cutting component positioning mechanism. The assembly mechanism is used to clamp the outer sleeve on the rotary detection mechanism and put it onto the cutting component to be assembled on the cutting component positioning mechanism.

[0012] The system also includes a second transport mechanism, which is mounted on the assembly platform and used to transfer the cutting components from the carrier to the cutting component positioning mechanism, and to transfer the assembled cutting components from the positioning mechanism to the next process. Compared to existing technologies, this solution achieves fully automated assembly through the coordinated operation of various mechanisms. This includes feeding the outer sleeve, detecting coaxiality rotation during assembly, fitting, feeding and positioning the cutting components to be assembled, and transferring the assembled cutting components. The assembly efficiency is high, eliminating the need for manual operation between mechanisms, greatly reducing labor intensity, and ensuring assembly quality.

[0013] To implement the cutting component positioning mechanism, in some preferred embodiments, the cutting component positioning mechanism includes a front positioning mechanism and a rear positioning mechanism arranged in parallel. The front positioning mechanism is used to clamp and position the assembled part of the cutting component to be assembled, and the rear positioning mechanism is used to clamp and position the unassembled part of the cutting component to be assembled. Since the cutting component is relatively long, the front positioning mechanism and the rear positioning mechanism work together to clamp and position the fitted part at the front end of the cutting component and the unfitted part at the rear end of the cutting component, respectively. The front positioning mechanism releases its grip during the fitting of the outer tube, while the rear positioning mechanism remains clamped throughout the fitting process, ensuring stable and reliable fitting of the outer tube.

[0014] To implement the front positioning mechanism, in some preferred embodiments, the front positioning mechanism includes a front positioning block and a front pressure plate disposed opposite each other. A front positioning groove is provided at one end of the front positioning block near the front pressure plate. The front positioning block is provided with a first driving mechanism for controlling its approach to or away from the cutting component, and a second driving mechanism is provided on the front positioning block for controlling its approach to or away from the cutting component. The first driving mechanism drives the positioning block to approach or move away, causing the cutting component to be positioned or disengaged from the front positioning groove. The second driving mechanism controls the front pressure block to approach or move away, causing the front pressure block to press against or detach from the cutting component, thereby achieving positioning, clamping, or releasing of the cutting component.

[0015] To implement the rear positioning mechanism, in some preferred embodiments, the rear positioning mechanism includes a rear positioning block and a rear pressure plate disposed opposite each other. A rear positioning groove is provided on one end of the rear positioning block near the rear pressure plate. A third driving mechanism is provided on the rear positioning block for controlling its approach to or movement away from the cutting component. The cutting component is placed in the rear positioning groove, and the third driving mechanism controls the rear pressure block to move closer to or further away, causing the rear pressure block to press against or detach from the cutting component, thereby achieving positioning, clamping, or releasing of the cutting component.

[0016] To implement the rotary detection mechanism, in some preferred embodiments, the rotary detection mechanism includes a clamping rotation mechanism for clamping and rotating the outer sleeve, and an attitude detection sensor. The attitude detection sensor is used to detect the runout amplitude when the clamping rotation mechanism clamps and rotates the outer sleeve, and to ensure the coaxiality of the outer sleeve with the cutting assembly to be assembled. By clamping and rotating the outer sleeve, and cooperating with the attitude detection sensor to detect the runout amplitude of the clamped outer sleeve during rotation, the coaxiality of the outer sleeve with the cutting assembly to be assembled is ensured.

[0017] To implement the assembly mechanism, in some preferred embodiments, the assembly mechanism includes a front assembly gripper and a rear assembly gripper arranged side by side. The front assembly gripper is provided with a fourth drive mechanism for controlling its gripping or releasing of the outer sleeve, and the rear assembly gripper is provided with a fifth drive mechanism for controlling its gripping or releasing of the outer sleeve. The assembly platform is provided with a sixth drive mechanism for driving the front and rear assembly grippers to reciprocate between the rotation detection mechanism and the cutting component positioning mechanism. Through the cooperation of the front and rear assembly grippers and the sixth drive mechanism, the clamping and assembly process of the sleeve is realized between the rotation detection mechanism and the cutting component positioning mechanism.

[0018] To implement the assembly mechanism, in some preferred embodiments, the assembly mechanism further includes a positioning adjustment mechanism disposed on the sixth drive mechanism. The rear assembly gripper is located between the positioning adjustment mechanism and the front assembly gripper. The positioning adjustment mechanism is used to abut against the end of the sleeve away from the sleeve and to ensure the coaxiality of the outer sleeve and the cutting component to be assembled. Because a coaxiality misalignment may occur at one end during the sleeve assembly, causing the other end of the outer sleeve to become skewed, resulting in a significant overall misalignment of the outer sleeve, assembly failure of the outer sleeve and cutting component is easily possible during the assembly process. To ensure the coaxiality of the outer sleeve and cutting component after clamping on the assembly mechanism, the positioning adjustment mechanism on the sixth drive mechanism ensures that the other end of the outer sleeve will never become skewed during the assembly process with the cutting component, guaranteeing stable and reliable assembly.

[0019] To implement the positioning and adjustment mechanism, in some preferred embodiments, the positioning and adjustment mechanism includes a positioning and adjustment block with a tapered hole. The larger end of the tapered hole is close to the rear-mounted gripper. The positioning and adjustment block is provided with a seventh drive mechanism for controlling its extension or retraction at the workstation. The first drive mechanism can control the positioning and adjustment block to be in its workstation position or retracted. Retraction is mainly to avoid interference when clamping the outer sleeve.

[0020] To achieve more precise clamping and assembly of the outer sleeve, in some preferred embodiments, the sixth drive mechanism is equipped with an eighth drive mechanism for simultaneously driving the front assembly gripper, the rear assembly gripper, and the positioning adjustment block to move closer to or further away from the outer sleeve. The eighth drive mechanism controls the front assembly gripper, the rear assembly gripper, and the positioning adjustment block to move closer to or further away from the outer sleeve, which also helps to better clamp the outer sleeve and allows for timely adjustment of the spacing for assembly in case of deviation, thereby improving assembly efficiency.

[0021] To better store the assembled cutting components, some preferred embodiments include a second hopper mechanism. The cutting component positioning mechanism is located between the conveying mechanism and the second hopper mechanism. The second hopper mechanism is mounted on the assembly platform and is used to store the assembled cutting components. The assembly platform is equipped with a third transport mechanism that transfers the cutting components assembled on the cutting component positioning mechanism to the second hopper mechanism. By setting up the second hopper mechanism, the assembled cutting components can be stored, facilitating centralized processing of the cutting components without manual intervention, achieving fully automated assembly and storage, and improving production efficiency.

[0022] The beneficial effects of this invention are as follows: The automatic assembly device for the outer sheath of the cutting component on a stapler, through the coordinated operation of various mechanisms, achieves fully automated assembly, including feeding the outer sheath, detecting coaxiality rotation during assembly, fitting, feeding and positioning the cutting component to be assembled, and transferring the assembled cutting component. This results in high assembly efficiency, eliminating the need for manual operation between mechanisms, significantly reducing labor intensity, and ensuring assembly quality. It avoids the problems of existing staplers using semi-automatic assembly of the outer sheath and cutting component installation, which relies on manual labor, significantly increasing the labor intensity of operators, and causing fatigue due to prolonged repetitive work, thus increasing the risk of misoperation and ultimately adversely affecting product consistency and quality stability.

[0055] The second hopper mechanism 10 is fixed on the assembly platform 1. The cutting component positioning mechanism 7 is located between the conveying mechanism 3 and the second hopper mechanism 10. The second hopper mechanism 10 is set on the assembly platform 1 and is used to store the assembled cutting components. The assembly platform 1 is provided with a third conveying mechanism 11 that transfers the assembled cutting components on the cutting component positioning mechanism 7 to the second hopper mechanism 10.

[0056] And a second transport mechanism 9, which is fixed on the assembly platform 1 and is used to transfer the cutting components on the carrier 2 to the cutting component positioning mechanism 7.

[0057] The cutting component positioning mechanism 7 includes three front positioning mechanisms 701 and one rear positioning mechanism 702 arranged in parallel. Each front positioning mechanism 701 includes a front positioning block 7011 and a front pressure plate 7012 arranged opposite to each other. A front positioning groove 7013 is provided on one end of the front positioning block 7011 near the front pressure plate 7012. The front positioning groove 7013 is a V-shaped groove. A first drive mechanism 7014 for controlling its approach or departure from the cutting component is provided on the front positioning block 7011. The first drive mechanism 7014 is a first telescopic cylinder. A second drive mechanism 7015 for controlling its approach or departure from the cutting component is provided on the front positioning block 7011. The second drive mechanism 7015 is a first rotary cylinder. The front positioning mechanism 701 clamps and positions the assembly part of the cutting component to be assembled. The rear positioning mechanism 702 includes a rear positioning block 7021 and a rear pressure plate 7022 arranged opposite to each other. A rear positioning groove 7023 is provided on the rear positioning block 7021 near the rear pressure plate 7022. The rear positioning groove 7023 is a V-shaped groove. A third drive mechanism 7024 is provided on the rear positioning block 7021 to control its approach or distance from the cutting component. The third drive mechanism 7024 is a second rotary cylinder. The rear positioning mechanism 702 clamps and positions the non-assembly part of the cutting component to be assembled.

[0058] The rotation detection mechanism 5 includes a clamping rotation mechanism 501 for clamping and driving the outer sleeve to rotate and an attitude detection sensor 502. The attitude detection sensor 502 is used to detect the runout amplitude when the clamping rotation mechanism 501 clamps and drives the outer sleeve to rotate and to ensure the coaxiality of the outer sleeve with the cutting component to be assembled.

[0059] Assembly mechanism 8 includes a front assembly gripper 801, a rear assembly gripper 802, and a positioning adjustment mechanism 806. The front assembly gripper 801 and the rear assembly gripper 802 are arranged side by side. The front assembly gripper 801 is equipped with a fourth drive mechanism 803 for controlling its gripping or releasing of the outer sleeve. The fourth drive mechanism 803 is a bidirectional synchronous cylinder. The rear assembly gripper 802 is equipped with a fifth drive mechanism 804 for controlling its gripping or releasing of the outer sleeve. The fifth drive mechanism 804 is also a bidirectional synchronous cylinder. The assembly platform 1 is equipped with a sixth drive mechanism 805 for driving the front assembly gripper 801 and the rear assembly gripper 802 to reciprocate between the rotation detection mechanism 5 and the cutting component positioning mechanism 7. The sixth drive mechanism 805 is a first linear module. The positioning adjustment mechanism 806 is mounted on the sixth drive mechanism 805. The rear assembly gripper 802 is located on the positioning adjustment mechanism. Between the assembly 806 and the front assembly gripper 801, the positioning adjustment mechanism 806 is used to abut against the end of the sleeve away from the sleeve and to ensure the coaxiality of the outer sleeve and the cutting component to be assembled. The positioning adjustment mechanism 806 includes a positioning adjustment block 8061, on which a tapered hole 8062 is opened. The diameter of the large end of the tapered hole 8062 is larger than the diameter of the outer sleeve. The large end of the tapered hole 8062 is close to the rear assembly gripper 802. The positioning adjustment block 8061 is provided with a seventh drive mechanism 8063 for controlling the extension or retraction at the work station. The seventh drive mechanism 8063 is a second telescopic cylinder. The sixth drive mechanism 805 is provided with an eighth drive mechanism 807 for driving the front assembly gripper 801, the rear assembly gripper 802 and the positioning adjustment block 8061 to move synchronously closer to or away from the outer sleeve. The eighth drive mechanism 807 is a third telescopic cylinder.

[0060] In this embodiment, the upper conveying mechanism 3 is a conveyor belt, which can realize the transport of the carrier 2 from the previous process to the next process. The rotating detection mechanism 5 includes a clamping rotating mechanism 501, which includes a clamping cylinder installed on the rotating end of the rotating cylinder. This can realize the clamping of the outer tube and also drive the outer tube to rotate after clamping. At the same time, the first transport mechanism 6, the second transport mechanism 9 and the third transport mechanism 11 all include a cylinder that can extend or retract on the moving end of the second linear module, and a gripper that can clamp the product is provided on the cylinder, so as to realize the transfer of the product from one process to another process.

[0061] Furthermore, the first hopper mechanism 4 and the second hopper mechanism 10 are located on the upper side of the upper surface of the assembly platform 1, the conveying mechanism 3 is located on the lower side of the upper surface of the assembly platform 1, and the rotation detection mechanism 5 and the cutting component positioning mechanism 7 are arranged opposite to each other and located in the middle of the upper surface of the assembly platform 1. That is, the rotation detection mechanism 5 and the cutting component positioning mechanism 7 are located between the first hopper mechanism 4, the second hopper mechanism 10 and the conveying mechanism 3.

[0062] The working principle of this solution is as follows: First, the assembled and cut components completed in the previous process are loaded onto the carrier 2 and transported to the workstation via the conveying mechanism 3. The second transport mechanism 9 controls the second linear module to move the gripper and clamp the cut component on the carrier 2, then transfers it to the cut component positioning mechanism 7. The first drive mechanism 7014 controls the front positioning block 7011 to rise and become flush with the rear positioning block 7021. The front positioning groove 7013 and the rear positioning groove 7023 correspond to each other. The first rotary cylinder at the second drive mechanism 7015 controls the front pressure plate 70 12. Rotate and open the front positioning groove 7013, and the second rotary cylinder at the third drive mechanism 7024 controls the rear pressure plate 7022 to rotate and open the rear positioning groove 7023. Then, the second transport mechanism 9 places the cutting component in the front positioning groove 7013 and the rear positioning groove 7023. Then, control the second drive mechanism 7015 to drive the front pressure plate 7012 to rotate and press on the cutting component, and control the third drive mechanism 7024 to drive the rear pressure plate 7022 to rotate and press on the cutting component, thus completing the positioning and clamping of the cutting component by the cutting component positioning mechanism 7.

[0063] Secondly, the first conveying mechanism 6 controls the second linear module to drive the gripper to move and clamp the outer tube in the first hopper mechanism 4, and then transfers it to the rotation detection mechanism 5. The rotation detection mechanism 5 clamps the outer tube and rotates it. When the outer tube rotates, the attitude detection sensor 502 detects the amplitude of the runout when the outer tube rotates to ensure the coaxiality of the outer tube with the cutting component to be assembled. After the detection is completed, if it does not meet the requirements, it is rejected by the first conveying mechanism 6. If it meets the requirements, it enters the next process to complete the rotation detection of the outer tube.

[0064] Then, the assembly mechanism 8 operates. The first linear module of the assembly mechanism 8 drives the front assembly gripper 801, the rear assembly gripper 802 and the positioning adjustment mechanism 806 to move towards the rotary detection mechanism 5. At this time, the second telescopic cylinder at the seventh drive mechanism 8063 drives the positioning adjustment block 8061 to retract, and controls the front assembly gripper 801 through the fourth drive mechanism 803 and the rear assembly gripper 802 through the fifth drive mechanism 804, simultaneously clamping the outer sleeve. The rotary detection mechanism 5 releases the outer sleeve, and the first linear module drives the front assembly gripper 801, the rear assembly gripper 802 and the positioning adjustment mechanism 806 to move towards the cutting component positioning mechanism 7. At the same time, it controls the second telescopic cylinder at the seventh drive mechanism 8063 to drive the positioning adjustment block 8061 to extend and be positioned at its work station. At this time, the outer sleeve corresponds to the tapered hole 8062 on the positioning adjustment block 8061 until the outer sleeve is opposite to the cutting component and enters the predetermined sleeve position.

[0065] During the fitting process, the first linear module drives the front assembly gripper 801, the rear assembly gripper 802, and the positioning adjustment mechanism 806 to slowly move towards the cutting component positioning mechanism 7 until one end of the outer sleeve is fitted onto the cutting component. As the first linear module slowly moves, the outer sleeve also gradually moves onto the cutting component. At this time, the four first drive mechanisms 7014 sequentially control the front positioning block 7011 to descend and be flush with and offset from the rear positioning block 7021, so that the front positioning groove 7013 and the rear positioning groove 7023 correspond. Simultaneously, the first rotary cylinder at the second drive mechanism 7015 controls the front pressure plate 7012 to rotate and open the front positioning groove 7013, making room for the cutting component to be assembled. As the outer sleeve gradually enters, the front assembly gripper 801 and the rear assembly gripper 802 release the outer sleeve. The outer sleeve abuts against the tapered hole 8062 on the positioning adjustment block 8061 for positioning and is pushed onto the cutting component until the outer sleeve is pushed to the required position on the cutting component, thus completing the assembly of the outer sleeve on the cutting component.

[0066] Finally, the assembled cutting component is clamped by the third transport mechanism 11 and transferred to the second hopper mechanism 10 for storage, thus completing the assembly of the cutting component. The above steps are then followed to assemble the next outer tube and cutting component in sequence.

[0067] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
