Description

Technical Field

[0001] The present invention relates to the technical field of handling equipment, and particularly to a multifunctional loading and unloading AGV device. Background Art

[0002] An AGV device refers to an unmanned automated vehicle with automatic guiding devices such as magnetic strips, tracks or lasers, traveling along a pre-planned path, powered by a battery, and equipped with safety protection and various auxiliary mechanisms (such as loading and unloading, assembly mechanisms).

[0003] Currently, the existing AGV devices have great limitations during use. That is, generally, the products produced on different production lines are relatively unified. Therefore, the same AGV device is matched according to different production lines. However, as enterprises develop, they will face different models of products. As a result, enterprises need to match different AGV devices according to the size of the products, which causes a huge burden on the enterprise's cost investment. At the same time, there are also differences in the shapes of different products. Therefore, when the AGV device passes through a bumpy section during transportation, the product will fall off the AGV device, resulting in damage to the product. Summary of the Invention

[0038] Embodiment 1:

[0039] This embodiment provides a multifunctional loading and unloading AGV device with the following technical features.

[0040] Please refer to Figure 1-8 , a multi-functional loading and unloading AGV device, including a moving device 1 and a transportation device 2 fixed on the upper part of the moving device 1. The transportation device 2 consists of: a frame 3, an X-direction adjustment mechanism, a Y-direction transportation mechanism, and a Z-direction fixing mechanism;

[0041] The X-direction adjustment mechanism includes a first guide rail 4, a first motor 5, a transmission screw 10, and a first guide rail 4 fixed on the frame 3. A first slider 8 is slidably connected to the upper part of the first guide rail 4. A transmission device 9 is fixedly connected to the upper part of the first slider 8. The output end of the first motor 5 is connected to two groups of transmission screws 10 through a belt. The transmission screw 10 is hinged to the transmission device 9;

[0042] Furthermore, the first guide rail 4 is perpendicular to the transmission device 9, and the transmission screw 10 is connected to the frame 3 through a bearing;

[0043] The Y-direction transportation mechanism includes two groups of second motors 11, a transmission rod 12, and another transmission device 9 fixed on the transportation device 2. The output end of the second motor 11 is connected to the transmission rod 12 through a belt. The transmission rod 12 penetrates through the transmission device 9 and extends to the other side of the frame 3. The transmission rod 12 is rotatably connected to the frame 3 through a bearing;

[0044] Furthermore, the transmission rod 12 is fixedly connected to the driving wheel 22 of the transmission device 9;

[0045] The Z-direction fixing mechanism includes a stepping motor 14, a guide rod 15, a guide block 16, a fixing plate 17, and a synchronous belt drive assembly 18 fixed on the frame 3. The output end of the stepping motor 14 is fixedly connected to the synchronous belt drive assembly 18. The synchronous belt drive assembly 18 is fixedly connected to the guide block 16 and drives the guide block 16 to move on the guide rod 15. The guide rod 15 is fixed on the frame 3, and the fixing plate 17 is fixedly connected to the guide block 16.

[0046] It should be noted that when the first motor 5 is started, the first motor 5 drives the transmission device 9 to rotate through the belt during operation. Since the transmission screw 10 is hinged to the transmission device 9, the transmission device 9 is driven to move. Since the first slider 8 is fixed to the lower part of the transmission device 9 and the first slider 8 slides on the first guide rail 4, the transmission device 9 moves in the X direction under the action of the first motor 5, facilitating the transmission device 9 to transport products of different sizes.

[0047] Start the second motor 11. When the second motor 11 operates, it drives the transmission rod 12 to rotate through a belt. Since the transmission rod 12 penetrates the conveying device 9 and is fixedly connected to the driving wheel 22, when the rotating rod 12 rotates, it drives the conveying device 9 to operate. The transmission rod (12) is rotatably connected to the machine frame (3) through a bearing. Therefore, when the transmission rod 12 is working, it will not drive the machine frame 3 to rotate. In summary, when the second motor 11 is working, it drives the conveying device 9 to work. Therefore, it drives the product to move in the Y direction.

[0048] Start the stepper motor 14. When the stepper motor 14 operates, it drives the synchronous belt transmission assembly 18 to work. When the synchronous belt transmission assembly 18 works, it drives the guide block 16 to move. Since the guide rod 15 is fixed on the machine frame 3 and the fixing plate 17 is fixedly connected to the guide block 16, when the stepper motor 14 works, it drives the fixing plate 17 to move on the guide rod 15, so that the fixing plate 17 fixes the product in the Z direction.

[0049] In an alternative embodiment, the synchronous belt transmission assembly 18 includes a second guide rail 19, a second slider 20, a synchronous pulley 21 and a synchronous belt fixed on one side of the machine frame 3. The two ends of the second guide rail 19 are provided with synchronous pulleys 21. A second slider 20 is connected between the two groups of synchronous pulleys 21 through a synchronous belt. The second slider 20 is slidably connected to the second guide rail 19. The second slider 20 is fixedly connected to the guide block 16. The stepper motor 14 is fixedly connected to the synchronous pulley 21.

[0050] It should be noted that when the stepper motor 14 is started, the stepper motor 14 drives the synchronous pulley 21 to rotate. At the same time, the synchronous pulley 21 drives the synchronous belt to rotate around the second guide rail 19. Since the synchronous belt is connected to the second slider 20, the second slider 20 slides on the second guide rail 19. Because the second slider 20 is fixedly connected to the guide block 16, when the stepper motor 14 is started, the guide block 16 moves on the second guide rail 19 following the second slider 20.

[0051] In an alternative embodiment, the conveying device 9 includes a driving wheel 22 penetrated by the transmission rod 12, a support frame 23, two groups of driven wheels 24 and two groups of guide wheels 25. The driving wheel 22, the driven wheels 24 and the guide wheels 25 are all installed on the support frame 23. The highest point of the guide wheel 25 is lower than the lowest point of the driven wheel 24. The belt sequentially bypasses the driven wheel 24, the highest point of the guide wheel 25, the lowest point of the driving wheel 22, the highest point of the other group of guide wheels 25 and the other group of driven wheels 24.

[0052] In an alternative embodiment, the transmission rod 12 is in the shape of a gear.

[0053] It should be noted that since the transmission rod 12 is gear-shaped, the driving wheel 22 can be driven to rotate by the transmission rod 12.

[0054] In an alternative embodiment, the mobile device 1 is composed of a housing 26, a driving wheel 27, and a caster wheel 28. The driving wheel 27 and the caster wheel 28 are both fixed to the lower part of the housing 26. The driving wheel 27 is fixed in the middle of the housing 26, and the caster wheel 28 is fixed at both ends of the housing 26.

[0055] It should be noted that the direction of the mobile device 1 is adjusted by the caster wheel 28, and the device is moved by the driving wheel 27.

[0056] In an alternative embodiment, a charging port 29 is provided at one end of the mobile device 1. The charging port 29 is electrically connected to a battery 30 fixed inside the mobile device 1.

[0057] It should be noted that the battery 30 inside the device can be charged through the charging port 29. The battery 30 is electrically connected to all the driving components inside the device to provide energy for all the driving components.

[0058] In an alternative embodiment, an emergency stop button 31 for the mobile device is also provided at one end of the mobile device 1.

[0059] In an alternative embodiment, a control panel 32 is installed on the frame 3. Power supply, start, and reset buttons are also provided on the frame 3 and distributed on both sides of the control panel 32.

[0060] The transportation device is controlled through the control panel 32, the power supply, start, and reset buttons on both sides of the control panel 32.

[0061] In an alternative embodiment, an emergency stop button 33 for the transportation device is also installed on the frame 3.

[0062] Working principle: The AGV device is moved to the end of the production line by the mobile device 1. The position of the conveyor device 9 is adjusted by starting the first motor 5 so that the distance between the two sets of conveyor devices 9 matches the size of the product. When the product on the production line comes into contact with the conveyor device 9, the second motor 11 is started. When the second motor 11 works, it drives the conveyor device 9 to work, moving the product on the production line onto the transportation device 9. The stepping motor 14 is started, and the stepping motor 14 drives the guide block 16 to move through the synchronous belt transmission assembly 18, so that the fixing plate 17 on the guide block 16 fixes the product on the conveyor device 9;

[0063] The AGV device is driven by the driving wheel 27 to move, and the direction is adjusted by the universal wheel 28, so that the device moves to the side of another production line. By starting the stepping motor 14, the fixing plate 17 pressing on the product moves upward to release the product, and then the second motor 11 is started. The product on the conveying device 9 is transported to another production line by the second motor 11.

[0064] In summary, for this multi-functional loading and unloading AGV device, by starting the first motor 5, when the first motor 5 works, it drives the conveying device 9 to rotate through the belt. Since the conveying screw 10 is hinged to the conveying device 9, the conveying device 9 is driven to move. Since the first slider 8 is fixed to the lower part of the conveying device 9 and the first slider 8 slides on the first guide rail 4, under the action of the first motor 5, the distance between the two groups of conveying devices 9 is adjusted, so as to facilitate the device to transport products of different sizes, thereby reducing the investment cost of the equipment.

[0065] For this multi-functional loading and unloading AGV device, start the stepping motor 14. When the stepping motor 14 works, it drives the synchronous belt transmission component 18 to work. When the synchronous belt transmission component 18 works, it drives the guide block 16 to move. Since the guide rod 15 is fixed to the frame 3 and the fixing plate 17 is fixedly connected to the guide block 16, when the stepping motor 14 works, it drives the fixing plate 17 to move on the guide rod 15, so that the fixing plate 17 fixes the product on the conveying device 9, avoiding the product from falling off the AGV device during transportation.

[0066] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0067] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
