Description

Technical Field

[0001] This utility model belongs to the field of workpiece machining technology, and in particular relates to a multi-station machining loading and unloading transmission line. Background Technology

[0002] The machining material handling conveyor line uses automated robotic arms to pick up and unload workpieces between the conveyor line and several machining units, reducing the waiting time for parts to turn around and be clamped between different machines, allowing for almost 24-hour uninterrupted production. The automated process reduces human intervention, significantly minimizing human error and resulting in extremely high product quality stability. A single conveyor line typically requires only 1-2 operators for monitoring, loading / unloading, and maintenance, reducing labor costs. Existing conveyor lines use a single-layer design; when incorporating vision inspection and hole detection stations, the design length of the conveyor line needs to be extended, resulting in a high space occupancy rate in the production workshop. Summary of the Invention

[0015] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 4 The multi-station machining loading and unloading transmission line shown includes a loading belt 1, an unloading belt 2, a first bracket 3, a second bracket 4, a drive motor 5, a lead screw 52, ​​a transmission sleeve 53, a base 6, a linear slide rail 7, a frame 8, a universal ball seat 81, a U-shaped plate 82, a guide rod 83, an electric push rod, and a control module. The feeding conveyor belt 1 and the unloading conveyor belt 2 are respectively fixedly installed on the upper and lower parts of the first bracket 3. The feeding conveyor belt 1 is provided with a clamping and fixing station 11. The second bracket 4 is fixedly installed on the base 6, the drive motor 5 is fixedly installed on the top of the second bracket 4, two linear slide rails 7 are fixedly installed on the base 6 through the support rod, a slider 71 is slidably installed on the linear slide rail 7, an electromagnet is fixedly installed on the top of the slider 71, the electric push rod is fixedly installed on the base 6, and the actuator of the electric push rod is fixedly connected to the slider 7. The upper and lower ends of the lead screw 52 are rotatably mounted on the top of the second bracket 4 and the base 6 respectively via ball bearings. The upper and lower ends of the guide rod 83 are fixedly mounted on the top of the second bracket 4 and the base 6 respectively. The transmission sleeve 53 is fixedly mounted on the U-shaped plate 82. The U-shaped plate 82 is fixedly connected to the frame 8. The top end of the lead screw 52 is connected to the output shaft of the drive motor 5. The transmission sleeve 52 is screwed and sleeved onto the lead screw 52. The U-shaped plate 82 is slidably sleeved onto the guide rod 83. The universal ball seats 81 are arranged in rows on the frame 8.

[0016] The second bracket 4 has a top drive seat 51, the drive motor 5 is fixedly mounted on the support seat 51, the lead screw 52 is rotatably connected to the support seat 51 through a ball bearing, and the upper end of the guide rod 83 is fixedly connected to the support seat 51. Compared with the second bracket 4, the support seat 51 has the advantage of being easy to install and connect with other components.

[0017] A guide sleeve is fixedly installed on the U-shaped plate 82. The guide sleeve is slidably fitted onto the guide rod 83 to improve the straightness of the up-and-down movement of the U-shaped plate 82 and avoid jamming problems.

[0018] The first support bracket 3 and the base 6 are respectively screwed onto the first support adjustment foot 31 and the second support adjustment foot 6. The height of the first support bracket 3 and the base 6 can be adjusted by the first support adjustment foot 31 and the second support adjustment foot 61 so that the height of the two can be matched.

[0019] L-shaped guard plates 80 are fixedly installed on both sides of the frame 8. The L-shaped guard plates 80 on both sides guide and restrict the workpiece carrier plate to prevent it from falling off from both sides of the universal ball seat 81.

[0020] The carrier plate for holding the workpiece flows along the feeding conveyor belt 1 to its clamping and fixing station 11, where it is clamped and fixed. This facilitates the automated robot arm to grip and load the workpiece between the carrier plate and the CNC machining equipment support. The drive motor drives the lead screw 52 to rotate forward, causing the transmission sleeve 53, U-shaped plate 82, frame 8, and universal ball seat 81 to move upward until the universal ball seat 81 is flush with the feeding conveyor belt 1. After the workpiece is processed, it flows along the carrier plate to the universal ball seat 81. The drive motor drives the lead screw 52 to rotate in the reverse direction until the universal ball seat 81 is flush with the unloading conveyor belt 2. The carrier plate, made of iron, is attracted and fixed by the energized electromagnet after contact. The actuator of the electric push rod extends and pushes the combination of slider 71, electromagnet, carrier plate, and workpiece to the left onto the unloading conveyor belt 2. It then continues to flow along the unloading conveyor belt 2 to the vision inspection station and hole inspection station for automated inspection.
