Description

Technical Field

[0001] This utility model belongs to the field of laser machining automation technology, and in particular relates to an automatic loading and unloading device for a laser machine with a double-layer material storage compartment. Background Technology

[0002] In the current field of laser machining automation, transport mechanisms are typically used to move raw materials from the loading station to the laser machine, where they are then processed before being transported to the unloading station. While this method is intuitive and easy to operate, the transport mechanism's speed is much higher than the laser machine's actual processing speed. This results in the transport mechanism being idle for most of the time while the laser machine is processing, leading to low overall equipment utilization. This idle time is particularly pronounced with large production batches and diverse products, thus increasing manufacturing costs. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic loading and unloading device for a laser machine with a two-layer material storage, which aims to solve the technical problem in the prior art that the transport mechanism is idle for most of the time when the laser machine is processing, resulting in a low utilization rate of the overall equipment.

[0004] To achieve the above objectives, this utility model provides an automatic loading and unloading device for a laser machine-supported double-layer material storage system, comprising a suspension arm, two laser machines, a loading trolley, a unloading trolley, and a transport device. The transport device includes two transport mechanisms. The two laser machines, the loading trolley, and the unloading trolley are all located below the suspension arm. The transport mechanisms are slidably mounted on the suspension arm, sliding over the laser machines, the loading trolley, and the unloading trolley. The transport mechanisms alternately place the material from the loading trolley onto the two laser machines, and then place the processed material from each laser machine onto the unloading trolley.

[0005] Furthermore, the transport mechanism includes a connecting arm, a mounting frame, and a pickup assembly. One end of the connecting arm is slidably connected to the suspension arm, and the other end of the connecting arm is connected to the mounting frame. A drive motor is installed at the connection point between the connecting arm and the suspension arm, and the drive motor is used to drive the connecting arm to move along the direction of the suspension arm. A lifting mechanism is also provided between the mounting frame and the pickup assembly. The lifting mechanism is fixedly mounted on the mounting frame, and the pickup assembly is connected to the drive end of the lifting mechanism. The lifting mechanism is used to control the raising or lowering of the pickup assembly.

[0006] Furthermore, the lifting mechanism includes a lifting motor, a transmission roller shaft, and two transmission components. The transmission roller shaft is rotatably mounted on the mounting frame, and the lifting motor drives the transmission roller shaft to rotate forward or backward. The two transmission components are respectively disposed opposite to each other at both ends of the transmission roller shaft. The transmission components include a transmission roller, two fixed pulleys, and two connecting belts. The transmission roller is fixedly connected to one end of the transmission roller shaft, and the two fixed pulleys are rotatably connected to the mounting frame and located on both sides of the transmission roller. One end of each connecting belt is connected to the upper and lower ends of the transmission roller, and the other end is connected to the pickup component after passing around the fixed pulleys on both sides. When the lifting motor drives the transmission roller shaft to rotate forward or backward, the transmission roller drives the connecting belts to wind up or unwind, thereby causing the pickup component to rise or fall.

[0007] Furthermore, the pickup assembly includes a pickup frame, a clamping drive, and two pickup arms. The pickup frame is connected to the transmission assembly, and the two pickup arms are respectively arranged opposite each other on both sides of the pickup frame. The two pickup arms are connected to the drive end of the clamping drive, and the clamping drive drives the two pickup arms to move closer or further apart from each other.

[0008] Furthermore, the clamping drive includes a clamping motor, a clamping roller shaft, and several clamping assemblies. The clamping roller shaft is rotatably connected in the pickup frame and perpendicular to the movement direction of the pickup arms. The clamping motor is mounted on the pickup frame and connected to the clamping roller shaft to drive its rotation. The clamping assemblies are mounted on the clamping roller shaft and connected to the two pickup arms to drive them closer together or further apart.

[0009] Furthermore, the clamping assembly includes a drive gear, a driven gear, and a transmission chain. The drive gear is connected to the clamping roller shaft, which drives the drive gear to rotate. The driven gear is rotatably mounted on the pickup frame. The transmission chain is sleeved on the drive gear and the driven gear, and meshes with them. The transmission chain is parallel to the direction of movement of the pickup arms. The two pickup arms are connected to the upper and lower ends of the transmission chain, respectively. The drive gear drives the transmission chain to move, thereby causing the two pickup arms to move closer or further apart.

[0010] Furthermore, the picking arm includes a connecting part connected to the drive chain and a carrying part for carrying materials. The carrying part includes several parallel carrying blocks, one end of each carrying block is connected to the connecting part, and the other end is used to extend into the bottom of the material.

[0011] Furthermore, the pickup assembly includes a suction plate and several suction nozzles. The suction plate is connected to each connecting belt, and the suction plates are distributed on the suction plate and are all connected to the negative pressure device.

[0012] The above-mentioned technical solutions of the automatic loading and unloading equipment for a laser machine with a two-layer material storage provided in this embodiment of the utility model have at least one of the following technical effects: the suspension arm is set on the loading trolley, the unloading trolley, and the two laser machines, and the two transport mechanisms are set on the suspension arm. The transport mechanisms move along the suspension arm on the loading trolley, the unloading trolley, and the two laser machines. First, one transport mechanism transports the raw material on the loading trolley to one laser machine, and then returns to the loading trolley to pick up the second piece of raw material and put it into the other laser machine. After the laser machine finishes processing, the other transport mechanism transports the processed material to the unloading trolley. Using the same transport mechanism for loading and unloading two laser machines improves the utilization rate of the transport mechanism, improves the working efficiency of the equipment, and reduces manufacturing costs.

[0021] In one embodiment of this utility model, reference is made to Figures 1-2As shown, an automatic loading and unloading device for a double-layer material storage silo with one laser machine supporting two laser machines is provided. It includes a suspension arm 100, two laser machines 200, a loading trolley 300, a unloading trolley 400, and a transport device 500. The transport device 500 includes two transport mechanisms 600. The two laser machines 200, the loading trolley 300, and the unloading trolley are all located below the suspension arm 100. The transport mechanisms 600 are slidably mounted on the suspension arm 100, and slide along the suspension arm 100 past the laser machines 200, the loading trolley 300, and the unloading trolley. The transport mechanisms 600 alternately place the materials from the loading trolley 300 onto the two laser machines 200, and place the processed materials from each laser machine 200 onto the unloading trolley 400. In this embodiment, the suspension arm 100 is mounted on the loading trolley 300, the unloading trolley 400, and the two laser machines 200. Two transport mechanisms 600 are mounted on the suspension arm 100. The transport mechanisms 600 move along the suspension arm 100 on the loading trolley 300, the unloading trolley 400, and the two laser machines 200. First, one transport mechanism 600 transports the raw material on the loading trolley 300 to one laser machine 200, and then returns to the loading trolley 300 to pick up a second piece of raw material and place it on the other laser machine 200. After the laser machine 200 finishes processing, the other transport mechanism 600 transports the processed material to the unloading trolley 400. By using the same transport mechanism 600 for loading and unloading the two laser machines 200, the utilization rate of the transport mechanism 600 is improved, the working efficiency of the equipment is increased, and the manufacturing cost is reduced.

[0022] Specifically, refer to Figures 1-2 As shown, the transport mechanism 600 includes a connecting arm 610, a mounting frame 620, and a pickup assembly 630. One end of the connecting arm 610 is slidably connected to the suspension arm 100, and the other end of the connecting arm 610 is connected to the mounting frame 620. A drive motor 640 is provided at the connection point between the connecting arm 610 and the suspension arm 100, and the drive motor 640 is used to drive the connecting arm 610 to move along the direction of the suspension arm 100. A lifting mechanism 650 is also provided between the mounting frame 620 and the pickup assembly 630. The lifting mechanism 650 is fixedly mounted on the mounting frame 620, and the pickup assembly 630 is connected to the drive end of the lifting mechanism 650. The lifting mechanism 650 is used to control the raising or lowering of the pickup assembly 630. In this embodiment, the drive motor 640 is used to drive the connecting arm 610 to move along the direction of the suspension arm 100, thereby driving the mounting frame 620 and the pickup component 630 to move on the loading trolley 300, the laser machine 200 and the unloading trolley. The lifting mechanism 650 is used to control the lifting of the pickup component 630, so that the pickup component 630 is close to the material for pickup.

[0023] Specifically, refer to Figures 1-2As shown, the lifting mechanism 650 includes a lifting motor 651, a transmission roller shaft 652, and two transmission components 653. The transmission roller shaft 652 is rotatably mounted on the mounting frame 620. The lifting motor 651 is used to drive the transmission roller shaft 652 to rotate forward or backward. The two transmission components 653 are respectively disposed at opposite ends of the transmission roller shaft 652. The transmission assembly 653 includes a transmission roller 654, two fixed pulleys 655, and two connecting belts 656. The transmission roller 654 is fixedly connected to one end of the transmission roller shaft 652.

One end of each connecting belt 656 is connected to the upper and lower ends of the transmission roller 654, and the other end is connected to the pickup assembly 630 after passing around the fixed pulleys 655 on both sides. When the lifting motor 651 drives the transmission roller shaft 652 to rotate forward or reverse, the transmission roller 654 drives the connecting belts 656 to wind up or unwind, thereby driving the pickup assembly 630 to rise or fall. In this embodiment, the transmission roller shaft 652 is controlled to rotate by the lifting motor 651, thereby driving the transmission roller 654 to rotate to wind up or unwind the connecting belts 656, so that the rising or falling distance of each belt connected to the pickup assembly 630 is consistent, keeping the rising or falling process of the pickup assembly 630 smooth.

[0024] Specifically, refer to Figures 1-2 As shown, the pickup assembly 630 includes a pickup frame 631, a clamping drive 632, and two pickup arms 633. The pickup frame 631 is connected to the transmission assembly 653. The two pickup arms 633 are respectively arranged opposite each other on both sides of the pickup frame 631, and the two pickup arms 633 are connected to the drive end of the clamping drive 632. The clamping drive 632 drives the two pickup arms 633 to move closer or further apart. In this embodiment, when it is necessary to pick up material, the clamping drive 632 first drives the two pickup arms 633 to move further apart. Then, the lifting mechanism 650 drives the pickup assembly 630 to descend until the pickup arms 633 are below the material. At this time, the clamping drive 632 drives the two pickup arms 633 to move closer together, so that the pickup arms 633 are below the material. The lifting mechanism 650 drives the pickup assembly 630 to rise, lifting the material and avoiding damage to the material processed by the laser machine 200.

[0025] Specifically, refer to Figures 1-2As shown, the clamping drive unit 632 includes a clamping motor 634, a clamping roller shaft 635, and several clamping assemblies 636. The clamping roller shaft 635 is rotatably connected to the pickup frame 631 and is perpendicular to the movement direction of the pickup arm 633. The clamping motor 634 is mounted on the pickup frame 631 and connected to the clamping roller shaft 635, used to drive the clamping roller shaft 635 to rotate. The clamping assemblies 636 are mounted on the clamping roller shaft 635 and connected to the two pickup arms 633, used to drive the two pickup arms 633 to move closer or further apart. In this embodiment, the clamping roller shaft 635 drives the clamping assemblies 636 to move, causing the pickup arms 633 to move closer or further apart, so that the distance traveled by each clamping assembly 636 driving the pickup arm 633 is consistent.

[0026] Specifically, refer to Figures 1-2 As shown, the clamping assembly 636 includes a drive gear 637, a driven gear 638, and a transmission chain 639. The drive gear 637 is connected to the clamping roller shaft 635, which drives the drive gear 637 to rotate. The driven gear 638 is rotatably mounted on the pickup frame 631. The transmission chain 639 is sleeved on the drive gear 637 and the driven gear 638, and meshes with them. The transmission chain 639 is parallel to the movement direction of the pickup arms 633. The two pickup arms 633 are connected to the upper and lower ends of the transmission chain 639, respectively. The drive gear 637 drives the transmission chain 639 to move, thereby causing the two pickup arms 633 to move closer or further apart. In this embodiment, the movement of the transmission chain 639 causes the pickup arms 633 to move closer or further apart, enabling relative movement between the two pickup arms 633.

[0027] Specifically, refer to Figures 1-2 As shown, the picking arm 633 includes a connecting part 6301 connected to the drive chain 639 and a supporting part 6302 for carrying materials. The supporting part 6302 includes several parallel supporting blocks 6303, one end of each supporting block 6303 is connected to the connecting part 6301, and the other end is used to extend into the bottom of the material.
