Description

Technical Field

[0001] This invention relates to the field of lifting spring hook technology, specifically to a lifting spring manipulator. Background Technology

[0002] Currently, there are two known types of spring forming equipment: cam-type spring machines and camless spring machines. Due to the appearance characteristics of springs, the forming steps are hook bending, straightening, coiling, hook bending, and double-hook spring bending. Furthermore, the mechanical performance stability of the equipment is limited, resulting in slow production speed and poor stability, which affects product performance and subsequent assembly and quality.

[0003] Based on this, the present invention designs a spring-loaded robotic arm to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a spring-loaded robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting spring manipulator, including a support frame, wherein a first picking gripper and a second picking gripper are fixedly installed on the upper end face of the support frame, and the first picking gripper and the second picking gripper are arranged perpendicularly.

[0006] The first material handling gripper has a suspension spring body located on its side near the rear end. A servo motor and a turntable are fixedly mounted on the support frame, and the turntable is fixedly mounted on the output shaft of the servo motor.

[0007] Preferably, the second picking claw is located on the upper end face of the support frame near the rear end, and the first picking claw is located on the upper end face of the support frame near one side.

[0008] Preferably, a telescopic cylinder and a push-tightening cylinder are fixedly installed on the upper end face of the support frame at a position in front of the second material handling claw, with the telescopic cylinder located on one side of the push-tightening cylinder.

[0009] Preferably, a hook mold is fixedly installed between the push-tightening cylinder and the second material handling jaw.

[0010] Preferably, the upper end face of the telescopic cylinder is provided with a rotating platform, and the upper end face of the rotating platform is located on the same horizontal line as the position of the hook mold.

[0011] Preferably, a drive motor is fixedly connected to the side of the hook mold.

[0012] Preferably, a bending die is provided on one side of the first material handling gripper, and the position of the turntable matches that of the bending die.

[0013] Preferably, the adjustment range of the bending and straightening mold is 0-360°.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. A robotic arm picks up the semi-finished spring body and places it into a bending mold. A servo motor drives a turntable via a reducer and gear transmission, simultaneously straightening one end of the spring body. After straightening, the robotic arm picks up the spring body and places it on a rotary table. The angle is adjusted according to the spring requirements. The spring body is then transferred by the robotic arm to a hook mold, where a pressing device tightens it to prevent the spring from wobbling. The servo motor then drives the hook mold device to form the spring. The spring machine produces the coiled portion, which is picked up by the robotic arm and placed into the bending mold. The mold is then controlled by a servo motor. The system uses a motor and gear drive for synchronous bending and straightening. The bending mold is adjustable from 0-360° according to the spring angle. The spring is then transferred by a robotic arm to a flipping mechanism where the bending mold direction is adjusted. The robotic arm then grips and places the spring into the bending mold, and a cylinder clamps the spring body. The bending mold bends synchronously. The length of the bending mold is adjustable according to the spring size, significantly increasing production speed. Mold-based production also ensures product dimensional consistency and stability. The process has been changed from two bending operations to one straightening operation, increasing forming speed. Standardized molds have been developed to address dimensional and stability issues.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 4 The present invention provides a lifting spring manipulator technical solution: the lifting spring manipulator includes a support frame 1, and a first picking claw 3 and a second picking claw 5 are fixedly installed on the upper end surface of the support frame 1. The first picking claw 3 and the second picking claw 5 are arranged vertically.

[0027] The first material handling gripper 3 has a suspension spring body 2 located on its side near the rear end. A servo motor 10 and a turntable 4 are fixedly installed on the support frame 1. The turntable 4 is fixedly installed on the output shaft of the servo motor 10.

[0028] The second picking claw 5 is located on the upper end face of the support frame 1 near the rear end, and the first picking claw 3 is located on the upper end face of the support frame 1 near one side.

[0029] The upper end face of the support frame 1 is fixedly installed with a telescopic cylinder 6 and a push-tightening cylinder 8 in front of the second material handling claw 5. The telescopic cylinder 6 is located on one side of the push-tightening cylinder 8. The angle is adjusted according to the requirements of the lifting spring. The lifting spring body 2 is transferred by the robot to the hook mold 7 and pushed tight by the push-tightening device to prevent the lifting spring from shaking.

[0030] A hook mold 7 is fixedly installed between the push cylinder 8 and the second material handling claw 5.

[0031] A rotating platform is provided on the upper end of the telescopic cylinder 6. The upper end of the rotating platform is on the same horizontal line as the hook mold 7. The robotic arm grabs and puts the hook mold 7 in, and the push cylinder 8 clamps the suspension spring body 2. The hook mold 7 bends the hook synchronously. The length of the hook mold can be adjusted according to the size of the suspension spring, which greatly improves the production speed and ensures the consistency and stability of the product size by producing it by mold.

[0032] A drive motor is fixedly connected to the side of the hook mold 7.

[0033] A bending mold 9 is provided on one side of the first material handling gripper 3, and the position of the turntable 4 matches that of the bending mold 9.

[0034] The adjustment range of the bending and straightening mold 9 is 0-360°.

[0035] A specific application of this embodiment is as follows: First, a robotic arm grasps the semi-finished product of the spring body 2 and places it into the bending mold 9. The servo motor 10 drives the turntable 4 through a reducer and gear transmission, simultaneously straightening one end of the spring body 2. After straightening, the robotic arm grasps the spring body 2 and places it on the rotary table. The angle is adjusted according to the requirements of the spring. The spring body 2 is transferred by the robotic arm to the hook mold 7, where it is pressed by a tightening device to prevent the spring from shaking. The hook mold 7 is then formed by the servo motor driving the spring machine. The spring machine produces the coiled part, which is grasped by the robotic arm and placed into the bending mold. In component 9, the mold is driven by a servo motor 10 and gears to simultaneously bend and straighten. The bending mold is adjustable from 0-360° according to the angle of the suspension spring. It is then transferred by a robotic arm to a flipping mechanism, where the direction of the hook mold 7 is adjusted. The robotic arm then grips and places the hook mold 7, and the cylinder 8 clamps the suspension spring body 2. The hook mold 7 simultaneously bends the hook. The length of the hook mold is adjustable according to the size of the suspension spring, thus greatly improving production speed. Mold production also ensures product dimensional consistency and stability. The original two-bending and two-straightening processes are changed to one-time forming, increasing forming speed by 50%. Standardized molds are developed to address dimensional and stability issues.
