[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0029] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0030] In the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] Example 1: Reference Figures 1-8, a laser navigation-based automobile parts three-dimensional warehouse handling equipment, including AGV handling equipment 1, a laser navigation system 11 for controlling the start and stop of the AGV handling equipment 1 is arranged inside the AGV handling equipment 1, and a liftable L-shaped load-bearing plate 2 is installed on one side of the AGV handling equipment 1, and also includes: a first placement box 3, which is arranged on the L-shaped load-bearing plate 2; a second placement box 31, which is symmetrically installed on both sides of the first placement box 3, and an expansion piece is provided on the first placement box 3 and the second placement box 31; a plurality of counterweight blocks 5, which are installed on one side surface of the L-shaped load-bearing plate 2, and contact the counterweight blocks 5 when the first placement box 3 moves to a certain distance on the first placement box 3, applying a vertical downward force to one side of the first placement box 3 in the upward state; when the first placement box 3 moves upward, a variable triangle area is formed with the two second placement boxes 31, and the two second placement boxes 31 are driven to move relative to each other through the linkage when moving upward, and when the first placement box 3 moves downward, the two second placement boxes 31 move in opposite directions.

[0032] In the present invention, the AGV handling equipment 1 includes a chassis, and a driving wheel and a driven wheel are installed at the bottom of the chassis. The driving wheel is driven by a DC motor and can realize straight-line walking and steering functions. The lifting mechanism adopts a hydraulic lifting system, which is composed of a hydraulic pump station, a hydraulic cylinder and a control valve. It can drive the L-shaped load plate 2 to perform lifting movements, so as to facilitate the movement of stored auto parts to a high place in the warehouse and realize the handling operation. The laser navigation system 11 is set up, and multiple laser emitters are installed on the top or wall of the warehouse. The laser beams emitted by the laser emitters form a series of grid lines on the warehouse floor. These grid lines serve as the navigation path for the equipment, guiding it to travel in the warehouse. A laser receiver is installed on the chassis of the equipment. The laser receiver can receive the laser signal emitted by the laser transmitter in real time and transmit the signal to the control system. The control system calculates the current position and posture of the equipment based on the received signal, thereby achieving precise navigation. This is a prior art and will not be described in detail here. However, in actual operation, due to the different sizes of auto parts on the opposite sides of the high-bay warehouse, coupled with errors in manual stacking and storage, and the complexity of stacking requirements, the width of the driving and handling channels in the warehouse is inconsistent. Some auto parts materials protrude and interfere, affecting the movement of the handling equipment and reducing the equipment's work efficiency. In this solution, the AGV handling equipment 1 uses a built-in laser navigation system 11 to achieve autonomous path planning and precise positioning in the high-bay warehouse. At the same time, a first placement box 3 and a second placement box 31 are provided on the L-shaped carrier plate 2 to form multiple storage areas, maximizing the storage capacity of the equipment for handling and transporting auto parts. When the equipment needs to pass through a narrow channel, the L-shaped carrier plate 2 drives the first placement box 3 to move vertically upward, and the linkage synchronously pulls the second placement boxes 31 on both sides to move symmetrically toward the center, forming a dynamically shrinking triangle. In the load-bearing area, during this process, the lifting action of the first placement box 3 and the horizontal displacement of the second placement box 31 form a linkage proportional relationship, which significantly reduces the overall width of the equipment and effectively breaks through the passage restrictions of traditional transportation equipment. The synchronous counterweight block 5 balances the center of gravity deviation in real time through the mechanical compensation mechanism to ensure transportation stability. When there are protruding and abnormally placed accessory materials on both sides of the driving channel, which affect the transportation of the accessory materials passing by, the first placement box 3 is moved up to a higher position in advance, and then moved down to trigger the reverse linkage mechanism: the second placement boxes 31 on both sides expand in the opposite direction along the track, and the two second placement boxes are used to increase the width of the equipment. The side of the placement box 31 implements adaptive squeezing and flattening of protruding accessories on the path to avoid the risk of equipment collision caused by abnormal placement of goods. The first placement box 3 and the second placement box 31 are provided with expansion parts inside. When the L-shaped load-bearing plate 2 is lifted as a whole and the transported accessories are moved to a higher place in the three-dimensional warehouse, the expansion parts produce an elastic jacking effect, causing the automotive accessories to rise in the first placement box 3 or the second placement box 31, greatly improving the operational convenience of mechanical grasping or manual unloading. This dual-mode linkage design not only enhances the adaptability to complex warehouse paths, but also achieves the coordinated optimization of loading and unloading efficiency and safety.

[0033] Example 2: Reference Figure 4 , which is basically the same as Example 1, and further: the expansion member includes a movable plate 32 that is slidably connected to the inner wall of the first placement box 3 and the second placement box 31, and a square airbag 33 is attached to the bottom of the movable plate 32. The three square airbags 33 are all installed on the inner wall of the first placement box 3 and the second placement box 31. One end of the square airbag 33 is connected to the air supply pipe 34, and one end of the air supply pipe 34 is installed with an air pump 35. A displacement sensor 36 is embedded in the interior of the movable plate 32, and a scale 6 is provided on one side of the inner wall of the first placement box 3 and the second placement box 31. The surface of the first placement box 3 and the second placement box 31 is provided with a wear-resistant coating.

[0034] Among them, the first placement box 3 or the second placement box 31 can store auto parts to be transported. When the L-shaped carrying plate 2 is lifted to a high position, the first placement box 3 and the second placement box 31 are also moved to the corresponding height, which is convenient for moving and transporting auto parts to a higher place in the warehouse for stacking and storage. When the parts in the first placement box 3 or the second placement box 31 are almost taken out and unloaded, the air pump 35 is started to inflate the interior of the square airbag 33, causing it to expand and then squeeze the movable plate 32 to move upward inside the first placement box 3 or the second placement box 31. In this way, the parts inside the first placement box 3 or the second placement box 31 can be lifted to a higher place in the first placement box 3 or the second placement box 31, which is convenient for the gripping robot to grip or manual unloading. Through this structural design , avoiding the situation in the prior art where some robotic arms are long and fixed, making it difficult to go deep into the first placement box 3 or the second placement box 31 to identify and grab accessories, or the situation where manual bending over to unload and carry accessories is labor-intensive, saving labor intensity and improving the accuracy of the robotic arm's grasping. At the same time, by setting a flexible structure at the bottom when carrying accessories, the handling equipment can play a vibration-reducing and buffering role for the carried accessories when walking on a bumpy and decelerating road section, further improving the equipment's operating stability. The displacement sensor 36 can be a commonly used model on the market. When the movable plate 32 is displaced, the displacement of the movable plate 32 can be measured, and the signal can be fed back to the control system. The displacement data can be observed, and the scale 6 can display the volume in the first placement box 3 or the second placement box 31.

[0035] Example 3: Reference Figure 2 、 Figure 4 、 Figure 6 and Figure 7, which is basically the same as Example 2, and furthermore, the linkage member includes a driving portion 41 fixedly mounted on the bottom of the first placement box 3, the driving portion 41 is fixedly mounted on the L-shaped carrier plate 2, one side of the first placement box 3 is fixedly connected to a limiting shaft 42, one end of the limiting shaft 42 is slidably connected to a T-shaped slide 43, the T-shaped slide 43 is provided on one side surface of the L-shaped carrier plate 2, the output end of the driving portion 41 is fixedly connected to a second rack 493, the surface of the second rack 493 is meshed with a second gear 492, and the axis of the second gear 492 is fixedly connected to a connecting rod 493. Connecting shaft 491, one end of the connecting shaft 491 is rotatably connected to the L-shaped load-bearing plate 2 through a bearing, one end of the connecting shaft 491 is fixedly connected to the first gear 49, the surface of the first gear 49 is meshed with the first rack 48, the bottom of the first rack 48 is fixedly connected to the connecting block 47, one end of the connecting block 47 is fixedly connected to the second placement box 31, the other end of the connecting block 47 is fixedly connected to the slide 44, the slide 44 is slidably connected to the slide rail 45, the slide rail 45 is installed on the side surface of the support plate 46, and the support plate 46 is fixedly installed on the surface of the L-shaped load-bearing plate 2.

[0036] Among them, when the AGV handling equipment 1 identifies the narrow aisle of the three-dimensional warehouse through the laser navigation system 11, the driving part 41 starts and drives the second rack 493 to move vertically, and transmits power to the first gear 49 through the transmission of the second gear 492 and the connecting shaft 491. During the engagement of the first gear 49 with the first rack 48, the connecting block 47 pulls and slides synchronously toward the center along the slide rail 45. At the same time, the limit shaft 42 is guided in the T-shaped slide groove 43 to ensure that the first placement box 3 is vertically lifted and lowered without deviation. In this stage, the transmission structure realizes mechanical decoupling control of lifting and retraction, so that the equipment can realize adjustment control of the width of the transported goods during transportation. The low-friction guide system composed of the support plate 46 and the slide 44 improves the smoothness of the movement of the second placement box 31. The above-mentioned transmission structure is designed through a ratio to ensure the normal operation of the horizontal movement and lifting movement of the first placement box 3 and the second placement box 31. Through this structure, during use, through the driving part 41 starts to drive the first placement box 3 to move upward, thereby causing the two second placement boxes 31 to move relative to each other, ensuring that when the handling equipment passes through a narrow channel, the overall width of the transported accessories can be adjusted and controlled, better adapting to walking through a narrow channel, effectively improving the flexibility of the device in complex conditions in the stereoscopic warehouse, and reducing the occurrence of low efficiency in detour driving; when walking in the channel in the warehouse, if there are some temporary and unevenly placed protruding accessory materials on both sides of the channel, which interfere with the normal driving of the handling equipment, at this time, after the first placement box 3 is lifted to a certain height, the first placement box 3 is then moved down and reset, and the two second placement boxes 31 are moved to the edges of the channels on both sides, and the protruding accessory materials are squeezed by the side of the second placement box 31, so that the stacked materials are more neat, so that the structure can also play a good leveling and correction effect when adjusting the overall width of the transported accessories, wherein the driving part 41 is replaced by a hydraulic rod drive.

[0037] Example 4: Reference Figure 4 and Figure 8, which is basically the same as Example 3, furthermore, there is an arc notch on the bottom surface of the three counterweight blocks 5, which is adapted to the limit shaft 42, and a positioning groove 51 is provided on the bottom surface of the counterweight block 5, and a positioning block 52 is fixed on the top of the counterweight block 5, which is adapted to the positioning groove 51. A side surface of the L-shaped bearing plate 2 is fixedly connected to a fixed block 53, one end of the fixed block 53 is rotatably connected to a rotating plate 54 through a pin, and one side of the rotating plate 54 is rotatably connected to a compression spring 56, one end of the compression spring 56 is rotatably connected to the fixed block 53 through a pin, and one end of the rotating plate 54 is fixed to a limit block 55. An opening is provided on the surface of the fixed block 53, and one end of the limit block 55 is clamped on the opening. One end of the rotating plate 54 fits with the bottom surface of two of the counterweight blocks 5, and a plurality of counterweight blocks 5 are arranged at equal intervals. One side of the three counterweight blocks 5 is fixedly connected to a T-block 511, and the T-block 511 is slidably connected in the T-slot 43.

[0038] In the present invention, when the AGV handling equipment 1 enters the narrow aisle of the three-dimensional warehouse through the laser navigation system 11, the driving part 41 drives the first placement box 3 to lift vertically, and the limit shaft 42 in the linkage part slides directionally along the T-shaped slide 43. At the same time, the three counterweights 5 are pulled to move synchronously by the T-shaped block 511 slidably connected in the slide. The arc notch at the bottom of the counterweight 5 is adapted to the curved surface of the limit shaft 42, and a positioning groove 51 and a positioning block 52 are provided. In combination with the gradient counterweight effect generated by the multiple counterweights 5 distributed at equal intervals, the counterweight 5 is lifted synchronously while the first placement box 3 is lifted, so that the center of gravity offset of the equipment is controlled within a controllable range. When the first placement box 3 moves downward, the two upper counterweights 5 are automatically reset. The locking action of the limit block 55 at one end of the rotating plate 54 in the opening triggers the mechanical self-locking, preventing the two upper counterweights 5 from moving downward, so that the three counterweights 5 are evenly spaced, ensuring the dynamic stability of the counterweight system when the first placement box 3 is lifted, and effectively reducing the occurrence of equipment tipping. It should be noted that a square notch is provided on the bottom surface of three of the counterweight blocks 5 on one side of the positioning groove 51. When the bottom counterweight block 5 moves up to the end, the bottom surface of the counterweight block 5 will not contact the rotating plate 54. When the two upper counterweight blocks 5 are reset and moved down, the elastic rebound of the compression spring 56 squeezes the rotating plate 54, so that one end of the rotating plate 54 is supported on the bottom surface of the counterweight block 5 through the square notch for limiting the position. The mass and quantity of the counterweight blocks 5 are adapted and designed according to the load-bearing limit values stored in the first placement box 3 and the second placement box 31.

[0039] The above embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patented invention. It should be noted that those skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention. These variations and improvements are equivalent modifications and improvements to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
