Description

Technical Field

[0001] This utility model belongs to the technical field of loading and unloading vehicles, and relates to an automatic loading and unloading vehicle for plastic product manufacturing. Background Technology

[0002] In the production of small plastic products, plastic crates are frequently used for transporting these products. Traditional handling methods rely mainly on manual labor, which is not only inefficient but also labor-intensive. While some companies have adopted automated handling equipment as industrial automation levels continue to improve, existing equipment often suffers from limitations such as single-function limitations and poor flexibility, making it difficult to accurately adapt to the handling needs of plastic crates of different sizes.

[0003] Therefore, we propose an automated loading and unloading vehicle for plastic product manufacturing, which can accurately position, flexibly stack, automatically load and unload, and stably transport plastic crates that need to be transferred, thereby improving production efficiency and reducing labor costs. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing an automatic loading and unloading transport vehicle for plastic product manufacturing. The technical problem this utility model aims to solve is: how to achieve precise positioning, automatic loading and unloading, stable handling, and flexible stacking of plastic crates that need to be transferred, thereby improving production efficiency and reducing labor costs.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automated loading and unloading transport vehicle for plastic product manufacturing includes an AGV trolley, a switching assembly, a clamping and lifting assembly, two symmetrically arranged transport assemblies, and two symmetrically arranged power storage conveyor belts. The switching assembly is located at the front end of the AGV trolley, and the clamping and lifting assembly is located at the front end of the switching assembly. The two transport assemblies are slidably arranged on the left and right sides of the front end of the clamping and lifting assembly, respectively, in a front-back direction. The two power storage conveyor belts are located on the left and right sides of the upper end of the AGV trolley, and the conveying rollers of the power storage conveyor belts are arranged in a left-right direction. A control unit, several laser sensors, and several vision sensors are fixed on the AGV trolley. The power storage conveyor belts, the switching assembly, the clamping and lifting assembly, the two transport assemblies, the several laser sensors, and the several vision sensors are all electrically connected to the control unit.

[0007] The working principle of this utility model is as follows: After receiving the handling instruction from the control unit, the AGV car detects the surrounding environment through laser sensors and vision sensors, plans the path, accurately locates the position of the plastic basket to be transported, and the AGV car automatically drives to the target location.

[0008] Once the designated position is reached, the control unit sends a command to the switching component. The switching component adjusts the position of the clamping lifting component so that it is aligned with the plastic basket. Then, the AGV moves forward so that the two transport components are located on both sides of the lower end of the plastic basket. The clamping lifting component is activated, which drives the transport component to clamp the plastic basket and then lifts the plastic basket vertically to place it on other plastic baskets for stacking.

[0009] After the palletizing is completed, the clamping and lifting component drives the transport component to clamp the bottom plastic crate of the plastic crate stack and lift it to the corresponding height of the power storage conveyor belt. The switching component then moves the plastic crate stack to the corresponding position of one of the power storage conveyor belts. The transport component slides backward and places the plastic crate stack on the power storage conveyor belt. The power storage conveyor belt then moves the plastic crate stack backward to facilitate the storage of the next plastic crate stack.

[0010] After the AGV has finished loading and unloading, it plans its return route again using laser and vision sensors, and automatically travels to the storage area for plastic products or the next processing station. Upon arrival at the destination, the power storage conveyor belt rotates in reverse, and the handling components work together to unload the plastic crates, completing a full automated loading and unloading process.

[0011] The AGV includes a frame with four Mecanum wheels evenly distributed in a rectangular array at the lower end. Mounting slots are opened on the left and right sides of the upper end of the frame. Two power storage conveyor belts are respectively installed inside the two mounting slots. A fence is fixed to the upper end of the frame, located on the left, right and rear sides of the two mounting slots. Mounting seats are fixed on the left and right sides of the front end of the frame. A switching component is located between the two mounting seats. All four Mecanum wheels are electrically connected to the control unit.

[0012] With the above structure, the frame serves as the main structure of the AGV, supporting and connecting other components. Four Mecanum wheels enable the AGV to move flexibly in different directions. The fence prevents the plastic crates from falling off during transportation, ensuring safety. The mounting slot accommodates the power storage conveyor belt, and the mounting base is used to install the switching components.

[0013] The switching assembly includes a square guide rail, a U-shaped long conditioner, a clamping plate, and an electric lead screw. The square guide rail is parallel to the conveyor roller of the power storage conveyor belt, and both ends of the square guide rail are fixedly connected to two mounting seats. The U-shaped opening of the U-shaped long conditioner faces the rear. The clamping plate is fixedly connected to the U-shaped opening of the U-shaped long conditioner. The square frame formed by the U-shaped long conditioner and the clamping plate is fitted onto the square guide rail. The electric lead screw is located behind the square guide rail, and both ends of the electric lead screw are fixedly connected to two mounting seats. The lead screw of the electric lead screw is parallel to the square guide rail. A connecting plate is fixed on the slider of the electric lead screw. The front end of the connecting plate is fixedly connected to the rear end of the clamping plate. A slide rail is fixed on the front end face of the U-shaped long conditioner. The slide rail is parallel to the square guide rail. The electric lead screw is electrically connected to the control unit.

[0014] With the above structure, the square guide rail provides a stable support and guiding foundation for the entire switching assembly. The electric lead screw drives the square frame formed by the U-shaped long condition and the clamping plate to move on the square guide rail, thereby driving the clamping lifting assembly and the conveying assembly to move, realizing flexible switching of clamping position, as well as switching between the storage positions of the two power storage conveyor belts. The slide rail is used to provide sliding guidance for the clamping lifting assembly.

[0015] The clamping and lifting assembly includes a bidirectional lead screw, a motor for driving the bidirectional lead screw to rotate, and two symmetrically arranged outer guide posts. The bidirectional lead screw is rotatably located at the upper end of the U-shaped section and is parallel to the square guide rail. The motor is located at the upper end of the U-shaped section. Moving blocks are respectively driven on the threaded sections at both ends of the bidirectional lead screw. The two moving blocks are symmetrically arranged. A slider is fixed on the rear end face of the lower end of each of the two outer guide posts. Both sliders are slidably mounted on the slide rail. A connecting plate II is fixed on each of the two moving blocks. The front end of the connecting plate II is respectively fixedly connected to the rear end face of the outer guide post on the same side. An inner guide post is slidably arranged vertically on the side end face of each of the two outer guide posts facing each other. A vertical electric push rod I is provided between the inner guide post and the outer guide post on the same side. The two ends of the electric push rod I are respectively hinged to the upper end of the inner guide post and the lower end of the outer guide post on the same side. The electric push rod I and the motor are electrically connected to the control unit.

[0016] With the above structure, after the AGV trolley is in place, the control unit sends a command to the motor, which starts and drives the bidirectional lead screw to rotate. The moving blocks at both ends of the bidirectional lead screw will move towards or away from each other along the bidirectional lead screw, and through the connecting plate two, drive the outer guide column to move horizontally along the slide rail, so as to adjust the distance between the two outer guide columns, so as to drive the handling component to clamp or release plastic baskets of different sizes. The control unit sends a command to the electric push rod one, which performs a telescopic action, thereby driving the inner guide column to rise and fall, completing the lifting or lowering operation of the plastic basket.

[0017] The conveying assembly includes a movable clamp, an electric push rod II, and a powered side-push conveyor belt. The movable clamp has an L-shaped cross-section. The vertical part of the L-shaped movable clamp is slidably mounted on the end face of the inner guide post away from the outer guide post in the front-back direction, and the horizontal part of the L-shaped movable clamp faces away from the inner guide post. The electric push rod II is fixedly mounted on the inner guide post in the front-back direction and is located above the movable clamp. The rear end of the movable clamp is fixedly connected to the telescopic end of the electric push rod II. The powered side-push conveyor belt is mounted on the vertical part of the L-shaped movable clamp and is located on the side of the movable clamp away from the inner guide post. The conveying rollers of the powered side-push conveyor belt are arranged in the vertical direction. Both the electric push rod II and the powered side-push conveyor belt are electrically connected to the control unit.

[0018] With the above structure, the L-shaped horizontal part of the movable clamping plate is used to clamp the lower end of the plastic box. When it is necessary to store the plastic box stack, the control unit will send a command to the electric push rod 2. The electric push rod 2 drives the movable clamping plate to slide backward, and then the power side push conveyor belt starts to work, pushing the plastic box onto the power storage conveyor belt or taking the plastic box off the power storage conveyor belt, realizing the transportation of the plastic box between different positions.

[0019] Compared with existing technologies, this automated loading and unloading vehicle for plastic product manufacturing has the following advantages:

[0020] 1. By combining AGV vehicles, laser sensors, vision sensors, and controllers, precise positioning and path planning functions can be achieved.

[0021] 2. By using AGV trolleys in conjunction with powered storage conveyor belts, stacked plastic boxes can be stored, enabling flexible and stable transfer of plastic boxes between two target locations.

[0022] 3. By combining the switching components, clamping lifting components, and handling components, it is possible to clamp and move plastic boxes of different sizes, thereby achieving efficient and stable transfer, stacking, and loading / unloading of plastic boxes, improving production efficiency and reducing labor costs.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-5 As shown, this automatic loading and unloading transport vehicle for plastic product manufacturing includes an AGV trolley 1, a switching assembly 3, a clamping and lifting assembly 4, two symmetrically arranged transport assemblies 5, and two symmetrically arranged power storage conveyor belts 2.

[0032] After reaching the designated position, the control unit sends a command to the switching component 3. The switching component 3 adjusts the position of the clamping lifting component 4 so that it is aligned with the plastic basket. Then, the AGV trolley 1 moves forward so that the two transport components 5 are located on both sides of the lower end of the plastic basket. The clamping lifting component 4 is activated, which drives the transport components 5 to clamp the plastic basket and then drives the plastic basket to be lifted vertically. The plastic basket is then placed on other plastic baskets for stacking.

[0033] After the palletizing is completed, the clamping lifting component 4 drives the conveying component 5 to clamp the bottom plastic basket of the plastic basket stack and lift it to the corresponding height of the power storage conveyor belt 2. The switching component 3 drives the plastic basket stack to the corresponding position of one of the power storage conveyor belts 2. The conveying component 5 slides backward and places the plastic basket stack on the power storage conveyor belt 2. The power storage conveyor belt 2 drives the plastic basket stack backward to facilitate the storage of the next plastic basket stack.

[0034] After the AGV trolley 1 has finished loading and transporting, it plans its return route again using laser sensors and vision sensors, and automatically travels to the storage area of ​​plastic products or the next processing station. Upon arrival at the destination, the power storage conveyor belt 2 rotates in the opposite direction, and the handling component 5 works in coordination to unload the plastic basket, completing a full automatic loading and unloading process.

[0035] The AGV trolley 1 includes a frame 6. The lower end of the frame 6 is provided with four Mecanum wheels 7 evenly distributed in a rectangular array.

The square guide rail 11 is parallel to the conveyor roller of the power storage conveyor belt 2, and both ends of the square guide rail 11 are fixedly connected to two mounting seats 10. The U-shaped opening of the U-shaped long condition 12 faces the rear. The clamping plate 13 is fixedly connected to the U-shaped opening of the U-shaped long condition 12. The square frame formed by the U-shaped long condition 12 and the clamping plate 13 is fitted onto the square guide rail 11. The rod 14 is located behind the square guide rail 11. The two ends of the electric lead screw 14 are fixedly connected to the two mounting bases 10 respectively, and the lead screw of the electric lead screw 14 is parallel to the square guide rail 11.

A slide rail 16 is fixed on the front end face of the U-shaped long condition 12. The slide rail 16 is parallel to the square guide rail 11. The electric lead screw 14 is electrically connected to the control unit.

[0038] In this embodiment, the square guide rail 11 provides a stable support and guiding foundation for the entire switching assembly 3. The electric lead screw 14 drives the square frame formed by the U-shaped long condition 12 and the clamping plate 13 to move on the square guide rail 11, thereby driving the clamping lifting assembly 4 and the conveying assembly 5 to move, realizing flexible switching of clamping position, as well as switching between the storage positions of the two power storage conveyor belts 2. The slide rail 16 is used to provide sliding guidance for the clamping lifting assembly 4.

[0039] The clamping and lifting assembly 4 includes a bidirectional lead screw 21, a motor 24 for driving the bidirectional lead screw 21 to rotate, and two symmetrically arranged outer guide posts 17. The bidirectional lead screw 21 is rotatably mounted on the upper end of the U-shaped long condition 12 and is parallel to the square guide rail 11. The motor 24 is mounted on the upper end of the U-shaped long condition 12. Moving blocks 22 are respectively driven on the threaded sections at both ends of the bidirectional lead screw 21. The two moving blocks 22 are symmetrically arranged. A slider 19 is fixed on the rear end face of the lower end of each of the two outer guide posts 17. Both sliders 19 are slidably mounted on... On the slide rail 16, two moving blocks 22 are each fixed with a connecting plate 23. The front end of the connecting plate 23 is fixedly connected to the rear end face of the outer guide post 17 on the same side. The two outer guide posts 17 are each provided with an inner guide post 18 in the vertical direction on the side end face facing each other. A vertical electric push rod 20 is provided between the inner guide post 18 and the outer guide post 17 on the same side. The two ends of the electric push rod 20 are respectively hinged to the upper end of the inner guide post 18 and the lower end of the outer guide post 17 on the same side. The electric push rod 20 and the motor 24 are electrically connected to the control unit.

[0040] In this embodiment, after the AGV trolley 1 is in place, the control unit sends a command to the motor 24, the motor 24 starts and drives the bidirectional lead screw 21 to rotate, the moving blocks 22 at both ends of the bidirectional lead screw 21 will move towards or away from each other along the bidirectional lead screw 21, and through the connecting plate 23, drive the outer guide column 17 to move horizontally along the slide rail 16, so as to adjust the distance between the two outer guide columns 17, so as to drive the conveying component 5 to clamp or release the plastic baskets of different sizes. The control unit sends a command to the electric push rod 20, the electric push rod 20 performs a telescopic action, thereby driving the inner guide column 18 to rise and fall, completing the lifting or lowering operation of the plastic basket.

[0041] The conveying assembly 5 includes a movable clamping plate 25, an electric push rod 26, and a powered side-push conveyor belt 27. The movable clamping plate 25 has an L-shaped cross-section. The vertical part of the L-shaped movable clamping plate 25 is slidably mounted on the end face of the inner guide post 18 away from the outer guide post 17 in the front-back direction, and the horizontal part of the L-shaped movable clamping plate 25 faces away from the inner guide post 18. The electric push rod 26 is fixedly mounted on the inner guide post 18 in the front-back direction and is located above the movable clamping plate 25. The rear end of the movable clamping plate 25 is fixedly connected to the telescopic end of the electric push rod 26. The powered side-push conveyor belt 27 is mounted on the vertical part of the L-shaped movable clamping plate 25 and is located on the side of the movable clamping plate 25 away from the inner guide post 18. The conveying rollers of the powered side-push conveyor belt 27 are arranged in the vertical direction. Both the electric push rod 26 and the powered side-push conveyor belt 27 are electrically connected to the control unit.

[0042] In this embodiment, the L-shaped horizontal portion of the movable clamping plate 25 is used to clamp the lower end of the plastic crate. When it is necessary to store a stack of plastic crates, the control unit will send a command to the electric push rod 26. The electric push rod 26 will drive the movable clamping plate 25 to slide backward, and then the power-driven side-push conveyor belt 27 will start working to push the plastic crates onto the power storage conveyor belt 2 or remove the plastic crates from the power storage conveyor belt 2, thereby realizing the transportation of plastic crates between different positions.

[0043] The working principle of this utility model is as follows: When the AGV trolley 1 receives the transport instruction from the control unit, it scans the surrounding environment, builds a map and plans the optimal path through the laser sensor and vision sensor it is equipped with, and accurately locates the target plastic basket. Then, the four Mecanum wheels 7 are flexibly turned under the drive of the control unit, and the trolley is smoothly driven to the destination.

[0044] Upon reaching the designated position, the control unit sends a signal to the switching component 3, and the electric lead screw 14 starts to operate, driving the U-shaped long conditioner 12 and the clamping plate 13 to slide along the square guide rail 11, adjusting the orientation of the clamping lifting component 4 so that it faces the plastic basket. Then, the AGV trolley 1 moves forward, allowing the two transport components 5 to reach the lower sides of the plastic basket. At this time, the clamping lifting component 4 starts under the control of the control unit, and the motor 24 drives the bidirectional lead screw 21 to rotate, driving the moving block 22 to move towards each other along the lead screw. Through the connecting plate 23, the outer guide column 17 is pushed to slide along the slide rail 16, so that the moving clamping plate 25 of the transport component 5 fits against the bottom of the plastic basket. At the same time, the electric push rod 20 extends, driving the inner guide column 18 to rise, clamping the plastic basket smoothly and lifting it vertically. After the single plastic basket is picked up, the operation can be repeated as needed to stack the plastic baskets.

[0045] After the palletizing is completed, the clamping and lifting component 4 is activated again, clamping the bottom plastic crate of the plastic crate stack and lifting it to the height corresponding to the power storage conveyor belt 2. The switching component 3 is then activated, moving the plastic crate stack to the corresponding position of one of the power storage conveyor belts 2. The electric push rod 26 of the transport component 5 pushes the moving clamp 25 to slide backward, so that the rear end of the moving clamp 25 is close to the corresponding power storage conveyor belt 2. The power side push conveyor belt 27 is activated, smoothly pushing the plastic crate stack onto the power storage conveyor belt 2. The power storage conveyor belt 2 operates, transporting the plastic crate stack backward, freeing up the front space to store new plastic crate stacks.

[0046] Once the AGV trolley 1 is loaded, the laser sensor and vision sensor replan the return path. The AGV trolley 1 travels to the storage area for plastic products or the next processing station. Upon arrival, the power storage conveyor belt 2 rotates in reverse, and the handling component 5 works in coordination to unload the plastic crates one by one, completing the entire automatic loading and unloading process. During the process, the guardrail 8 on the frame 6 prevents the plastic crates from falling and ensures transportation safety.

[0047] In summary, by combining the AGV vehicle 1, laser sensors, vision sensors, and controller, precise positioning and path planning functions are achieved.

[0048] By cooperating with the AGV trolley 1 and the powered storage conveyor belt 2, stacked plastic crates can be stored, enabling flexible and stable transfer of the plastic crates between two target locations.

[0049] By combining the switching component 3, the clamping and lifting component 4, and the handling component 5, it is possible to clamp and move plastic crates of different sizes, thereby enabling efficient and stable transfer, stacking, and loading / unloading of plastic crates, improving production efficiency and reducing labor costs.
