Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a feeding device for an automated production line for laser cleaning of the outer wall of complex curved valves. Background Technology

[0002] There are two main existing technologies for rust removal from the outer walls of complex curved valves: high-pressure water cleaning and shot blasting. However, both methods have reached their technological limits. High-pressure water cleaning cannot effectively remove paint from valve components. After secondary ultrasonic cleaning, the previously well-adhered paint may soften and peel off, causing secondary contamination of the valve's internal channels. Shot blasting can effectively clean surface paint and rust, but for valve components with high internal precision, there is a risk of steel shot entering the interior, causing malfunction.

[0003] Laser cleaning technology has been widely applied in various fields, but for valve components with complex curved surfaces, manual laser cleaning is still the primary method, and there is currently no automated production line capable of achieving batch, high-efficiency cleaning. Therefore, we plan to develop and design a corresponding automated laser cleaning production line. This automated production line will generally include a pallet conveyor, a laser cleaning unit, a unloading unit, and a material frame conveyor. The pallet conveyor will automatically transport the workpieces and pallets; the laser cleaning unit will automatically perform laser cleaning on the workpieces; the unloading unit will transfer the cleaned workpieces to the material frame conveyor; and the material frame conveyor will then transfer the cleaned workpieces to the next process step.

[0004] Currently, valve components with complex curved surfaces are mainly cleaned manually using lasers. Therefore, there are no mature automated production line technologies to refer to. In the design and development of the entire production line, the feeding device, which serves as the link between the pallet conveyor and the material frame conveyor, has a key technical problem that needs to be solved: how to design its structure to ensure a good connection. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for an automated production line for laser cleaning of complex curved valve outer walls. This feeding device can automatically transfer the laser-cleaned workpiece from the pallet conveyor to the material frame of the material frame conveyor, playing a good connecting role, ensuring the smooth operation of the entire automated production line, and improving the laser cleaning efficiency of the workpiece.

[0006] The technical solution of this utility model is as follows: a feeding device for an automated production line for laser cleaning of complex curved valve outer walls, comprising a mounting gantry, a linear module and a guide rail arranged on the top of the mounting gantry along its width direction, a mounting plate fixed on the slider of the linear module, a guide block also mounted on the mounting plate, the guide block slidably connected to the guide rail, a lifting cylinder vertically mounted on the mounting plate, the push rod of the lifting cylinder passing through the mounting plate and fixedly connected to the lifting plate below it, a gripper rotatably mounted on the bottom of the lifting plate, a gripper cylinder rotatably mounted on the lifting plate, and the push rod of the gripper cylinder connected to the gripper.

[0007] In the aforementioned unloading device of an automated production line for laser cleaning of complex curved valve outer walls, the gripper consists of a symmetrically arranged left gripper and a right gripper. The top of the left gripper and the right gripper are rotatably connected to the bottom of the lifting plate. The bottom of the gripper is also provided with a notch. The outer side walls of the left gripper and the right gripper are each rotatably connected to the push rod of a gripper cylinder.

[0008] In the aforementioned unloading device of an automated production line for laser cleaning of complex curved valve outer walls, a bayonet is provided on each of the left and right edges of the lifting plate, and a hinge support is provided on the top surface of the lifting plate at the bayonet. The tail end of the gripper cylinder is hinged to the hinge support, and its body passes through the bayonet and its head end is rotatably connected to the outer wall of the left or right gripper.

[0009] In the aforementioned unloading device of an automated production line for laser cleaning of complex curved valve outer walls, multiple guide columns are vertically installed on the lifting plate, with the guide columns extending upward and passing through the guide sleeves provided on the mounting plate.

[0010] In the aforementioned unloading device of an automated production line for laser cleaning of complex curved valve outer walls, a guide rail is provided on each side of the linear module, and two guide blocks are provided on each side of the bottom of the mounting plate.

[0011] In the aforementioned automated production line for laser cleaning of complex curved valve outer walls, two sets of the unloading device are provided, both installed on the left and right sides of the top of the same mounting gantry.

[0012] In the aforementioned unloading device of an automated production line for laser cleaning of complex curved valve outer walls, contact sensors are provided on the mounting gantry directly in front of and behind the mounting plate.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model, by setting up components such as a linear module, mounting plate, lifting cylinder, lifting plate, gripper, and gripper cylinder, allows the lifting cylinder to drive the lifting plate downwards during use, and the gripper cylinder to drive the gripper to close, thereby clamping the laser-cleaned workpiece. The linear module drives the mounting plate to move linearly along the guide rail, and the downward movement of the lifting plate and the opening of the gripper automatically transfer the cleaned workpiece from the pallet conveyor to the material frame conveyor, playing a good connecting role, ensuring the smooth operation of the entire automated production line, and improving the laser cleaning efficiency of the workpiece.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] An embodiment of this utility model: A feeding device for an automated production line for laser cleaning of complex curved valve outer walls includes a mounting gantry 1. A linear module 2 and a guide rail 3 are arranged on the top of the mounting gantry 1 along its width direction. A mounting plate 4 is fixed on the slider of the linear module 2. A guide block 5 is also installed on the mounting plate 4. The guide block 5 is slidably sleeved with the guide rail 3. A lifting cylinder 6 is vertically installed on the mounting plate 4. The push rod of the lifting cylinder 6 passes through the mounting plate 4 and is fixedly connected to the lifting plate 7 below it. A gripper 8 is rotatably installed at the bottom of the lifting plate 7. A gripper cylinder 9 is also rotatably installed on the lifting plate 7. The push rod of the gripper cylinder 9 is connected to the gripper 8.

[0019] A material frame conveying device is horizontally installed at the end of the pallet conveyor line. The pallet conveyor line and the material frame conveying device are arranged in a T-shape. The mounting gantry 1 of this utility model is preferably set at the end of the pallet conveyor line and directly above the material frame conveying device. When the laser-cleaned pallet is conveyed to its end position by the pallet conveyor line, the push rod of the lifting cylinder 6 pushes out, driving the lifting plate 7 to descend. At this time, the gripper 8 rotates outward and opens under the driving action of the gripper cylinder 9. After the laser-cleaned workpiece enters the gripper 8, the lifting cylinder 6 stops descending, and the gripper 8 rotates inward and closes under the driving action of the gripper cylinder 9, clamping the workpiece. Then, the lifting cylinder 6 drives the lifting plate 7 to rise. Then, the linear module 2 moves, driving the mounting plate 4 and the lifting plate 7. The components move together from the front of the mounting gantry 1 along the guide rail 3 in a straight line to the rear. After moving to the rear of the mounting gantry 1, they are positioned directly above the material frame conveying device. Then, the linear module 2 stops moving, the lifting cylinder 6 drives the lifting plate 7 to descend, and the gripper 8 rotates outward and opens under the drive of the gripper cylinder 9, so that the workpiece gripped by the gripper 8 falls into the material frame on the material frame conveying device. The material frame is then conveyed to the next process by the material frame conveying device. The entire unloading process is completed, and the unloading device returns to its original position for the next gripping operation.

[0020] The gripper 8 consists of a symmetrically arranged left gripper 801 and a right gripper 802. The left gripper 801 and the right gripper 802 have a structure similar to a bucket. The tops of the left gripper 801 and the right gripper 802 are rotatably connected to the bottom of the lifting plate 7. The bottom of the gripper 8 is also provided with a notch 803. The outer walls of the left gripper 801 and the right gripper 802 are each rotatably connected to the push rod of a gripper cylinder 9. When the gripper cylinder 9 retracts, because the tops of the left gripper 801 and right gripper 802 are rotatably connected to the bottom of the lifting plate 7, and the push rod is rotatably connected to the outer walls of the left gripper 801 and right gripper 802, they cannot move upwards in a straight line. At this time, the gripper cylinder 9 will drive either the left gripper 801 or the right gripper 802 to rotate around the connection point with the lifting plate 7, causing the left gripper 801 and right gripper 802 to open outwards, allowing the workpiece held by the gripper 8 to fall down. When it is necessary to grip the workpiece, the gripper cylinder 9 is controlled to push outwards. At this time, the gripper cylinder 9 will drive either the left gripper 801 or the right gripper 802 to rotate around the connection point with the lifting plate 7, causing the left gripper 801 and right gripper 802 to close inwards, thereby gripping the workpiece. Since the workpieces are placed on pallets on the pallet conveyor line, to prevent the grippers 8 from directly clamping the sides of the workpieces and causing damage, a workpiece lifting mechanism is installed below the end of the pallet conveyor line. The lifting mechanism uses a push rod to lift the workpiece to a certain height, making it easier for the grippers 8 to grasp it. Similarly, to prevent the grippers 8 from directly contacting the push rod of the lifting mechanism when grasping the workpiece, a semi-circular notch 803 is provided at the bottom of both the left gripper 801 and the right gripper 802. During workpiece grasping, the push rod engages precisely in the notch 803, thus preventing contact between the grippers 8 and the push rod.

[0021] The lifting plate 7 has a latch 13 on each of its left and right edges. A hinge support 14 is provided on the top surface of the lifting plate 7 at the latch 13. The tail end of the gripper cylinder 9 is hinged to the hinge support 14, and its body passes through the latch 13 and its head end is rotatably connected to the outer wall of the left gripper 801 or the right gripper 802. When the gripper cylinder 9 is pushed out or retracted, it rotates around the connection point of the hinge support 14, and drives the left gripper 801 or the right gripper 802 to rotate around the connection point with the lifting plate 7, thereby opening or closing the left gripper 801 and the right gripper 802.

[0022] Four guide columns 10 are vertically installed at the four corners of the upper edge of the lifting plate 7. The guide columns 10 extend upward and pass through the guide sleeves 11 provided on the mounting plate 4. This structure ensures the stability of the lifting plate 7 when it moves up and down in a straight line.

[0023] The linear module 2 has a guide rail 3 on each side, and the mounting plate 4 has two guide blocks 5 on each side of the bottom. This structure ensures the stability of the mounting plate 4 when running in a straight line.

[0024] Two sets of the unloading device are provided, both installed on the left and right sides of the top of the same mounting gantry 1. Having two sets of unloading devices corresponds to two pallet conveyor lines, and each pallet conveyor line is equipped with a corresponding laser cleaning device, thus improving laser cleaning efficiency.

[0025] Contact sensors 12 are provided on the mounting gantry 1 directly in front of and behind the mounting plate 4. When the mounting plate 4 moves forward or backward under the drive of the linear module 2 and comes into contact with the contact sensor 12, it indicates that the mounting plate 4 has moved forward or backward to the corresponding position. The contact sensor 12 will send a signal to the controller of the automated production line. After receiving the signal, the controller will control the linear module 2 to stop running.
