Description

Technical Field

[0001] This utility model relates to the field of automated production equipment technology, specifically to a feeding device and a discharging device for surface milling. Background Technology

[0002] In production lines for bamboo and wood products, the inter-station conveying of workpieces is a critical link. Traditional production relies heavily on manual feeding, which presents the following problems: First, manual conveying is inefficient and difficult to match the operating rhythm of high-speed production lines; second, manual positioning accuracy is poor, and workpiece placement deviations can easily lead to errors in subsequent processing; third, long-term manual operation can easily cause fatigue, increasing the risk of workpiece damage or personnel safety hazards.

[0003] While existing robotic feeding devices have achieved partial automation, they generally suffer from insufficient positioning accuracy, are still unable to meet the conveying needs of irregularly shaped bamboo and wood products, and lack real-time obstacle avoidance functions, making it difficult to meet the production requirements of high precision, speed, and safety. To address this, we propose a surface milling feeding and discharging device. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device and a discharging device for surface milling, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loading and unloading device for surface milling, comprising a frame, a loading mechanism fixedly connected to the top right side of the frame, an unloading mechanism fixedly installed on the top left side of the frame, a slide rail installed at the top center of the frame, a work platform that can slide left and right mounted on the slide rail, a drive mechanism for moving the work platform mounted on one side of the slide rail, preferably a combination of a servo motor and a ball screw, with a positioning accuracy of ±0.05mm, a bracket fixedly installed on the front right side of the frame, a hopper platform fixedly installed on the top of the bracket, and pneumatic clamps mounted on both the work platform and the hopper platform.

[0006] Optionally, the feeding mechanism includes a first mounting frame, a first fixed frame, a first translation cylinder, a first moving frame, a first lifting cylinder, and a first robotic arm. The first mounting frame is fixedly installed on the top right side of the frame, and the first fixed frame is fixedly installed on the top left side of the first mounting frame.

[0007] Optionally, a first translation cylinder is fixedly installed on the first fixed frame, and the telescopic end of the first translation cylinder passes through the first fixed frame and extends to the outside of the first fixed frame and is fixedly connected to a first movable frame.

[0008] Optionally, a first lifting cylinder is fixedly installed on the top of the first movable frame. The telescopic end of the first lifting cylinder passes through the first movable frame and extends to the outside of the first movable frame, and is detachably connected to a first robotic arm.

[0009] Optionally, the unloading mechanism includes a second mounting frame, a second fixed frame, a second translation cylinder, a second moving frame, a second lifting cylinder, and a second robotic arm. The second mounting frame is fixedly installed on the top left rear of the frame, and the second fixed frame is fixedly installed on the second mounting frame.

[0010] Optionally, a second translation cylinder is fixedly installed on the rear side of the second fixed frame. The telescopic end of the second translation cylinder passes through the second fixed frame and extends to the outside of the second fixed frame and is fixedly connected to the second movable frame.

[0011] Optionally, a second lifting cylinder is fixedly installed on the top of the second movable frame. The telescopic end of the second lifting cylinder passes through the second movable frame and extends to the outside of the second movable frame, and is detachably connected to a second robotic arm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. High degree of automation: No manual intervention is required throughout the entire process. The feeding mechanism automatically grabs the workpiece to be processed and transports it to the work platform, and the unloading mechanism automatically grabs the processed workpiece and transports it to the designated area, realizing full automation of the "feeding-processing-discharging" process. The production line conveying efficiency is increased by more than 50%, matching the working rhythm of high-speed curved surface milling equipment.

[0013] 2. Safe and reliable: The feeding and unloading mechanisms are driven by cylinders to achieve large-span lifting and translation, which can avoid obstacles (such as equipment protrusions and foreign objects) on the conveying path in real time, reducing safety risks.

[0014] 3. High versatility: The first and second robotic arms adopt a detachable design. When changing the type of workpiece, only the appropriate gripper needs to be disassembled and replaced. There is no need to design a separate conveying device for a single workpiece, which greatly reduces the equipment investment cost. It is suitable for curved surface milling production lines for various bamboo and wood products.

[0015] 4. The working platform is moved by a drive mechanism, and the pneumatic clamps are used for precise fixation to solve the problem of manual positioning deviation. Attached Figure Description
