Description

Technical Field

[0001] This utility model relates to the field of unmanned transport vehicle technology, specifically a transport device for the construction of an unmanned digital workshop. Background Technology

[0002] In the process of industrial intelligent transformation, unmanned digital workshops, as the core scenario of intelligent manufacturing, have put forward stringent requirements for the automation, precision and efficiency of material transportation. At present, the docking and positioning of unmanned transport equipment and material pallets mostly rely on traditional data positioning methods, mainly by collecting environmental data through high-precision sensors and combining complex algorithms for position calibration in order to achieve docking between the two.

[0003] However, this type of data positioning method has many limitations in practical applications: First, the positioning efficiency is low. Unmanned transport equipment needs to undergo multiple precise position adjustments to complete docking. These repeated adjustments are time-consuming and can easily lead to a decrease in workshop logistics efficiency. Second, due to the influence of external factors such as the environment, sensor signal acquisition and data transmission are easily interfered with, often resulting in slight positioning deviations, which can easily lead to docking failure.

[0004] To address these issues, we provide transportation equipment for the construction of unmanned digital workshops. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a transport device for the construction of an unmanned digital workshop. By cooperating with components such as the sliding rod at the lower end of the pallet and the positioning mechanism, it solves the problem that traditional unmanned transport devices rely heavily on traditional data positioning methods when docking and positioning with material pallets. These methods have low positioning efficiency and are easily affected by signal interference, leading to docking deviations.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a transport device for the construction of an unmanned digital workshop, including an unmanned transport vehicle, wherein a matching pallet is provided on the upper end of the unmanned transport vehicle;

[0009] The front and rear ends of the tray are connected to first sliding rods, and the two sides of the tray are connected to second sliding rods.

[0010] The unmanned transport vehicle is equipped with a positioning mechanism, which includes:

[0011] Two first positioning blocks are set at the front and rear ends. The lower end of the first positioning block is connected to a first telescopic rod, which is set vertically.

[0012] The second positioning blocks are set on both sides, and the lower end of the second positioning blocks is connected to the second telescopic rod, which is set vertically.

[0013] The third telescopic pole is connected to the body of the unmanned transport vehicle. The drive end of the third telescopic pole is connected to the second telescopic pole. The third telescopic pole is set horizontally.

[0014] Furthermore, the lower end of the tray is connected to a support leg plate, the lower end of the support leg plate is connected to a base plate, and the lower end of the base plate is connected to a rubber pad with an anti-slip texture on its surface.

[0015] Furthermore, the upper edge of the tray is connected to a frame, and the frame has multiple round holes.

[0016] Furthermore, a positioning groove frame is connected to the lower surface of the tray, and the positioning groove frame is located at the center end of the tray.

[0017] Furthermore, the sides of the first slide rod and the second slide rod are set as smooth inclined surfaces, and the sides of the first positioning block and the second positioning block are set as smooth inclined surfaces. The smooth inclined surface of the first positioning block can interact with the smooth inclined surface of the first slide rod, and the smooth inclined surface of the second positioning block can interact with the smooth inclined surface of the second slide rod.

[0018] Furthermore, the unmanned transport vehicle is connected to support rods at the front and rear ends, the first telescopic rod is connected to the side end of the support rod, the front end of the unmanned transport vehicle is connected to a control box, and the lower end is equipped with multiple steerable drive wheels and auxiliary omnidirectional wheels.

[0019] Furthermore, the upper center end of the unmanned transport vehicle is connected to multiple No. 4 telescopic rods, and the driving end of the No. 4 telescopic rods is connected to a fixing plate, which can be inserted into the positioning slot frame at the lower end of the tray.

[0020] (iii) Beneficial effects:

[0021] Compared with existing technologies, the transportation equipment used for constructing this unmanned digital workshop has the following advantages:

[0022] I. The transport equipment used in the construction of this unmanned digital workshop is equipped with a first sliding rod, a second sliding rod, a first positioning block, and a second positioning block. The first positioning block, pushed by a first telescopic rod, uses its inclined surface to interact with the inclined surface of the first sliding rod to achieve front-to-back positioning. The second positioning block, pushed by a second telescopic rod, uses its inclined surface to interact with the inclined surface of the second sliding rod to achieve lateral positioning. If the material on the pallet is light, the horizontal thrust generated by the interaction of the positioning block and the sliding rod will be able to move the pallet to the center of the unmanned transport vehicle; if the material on the pallet is heavy, the interaction of the positioning block and the sliding rod will... The resulting thrust will act in the opposite direction to the unmanned transport vehicle, which passively moves to the center of the pallet. This adaptive adjustment mechanism ensures accurate docking between the pallet and the unmanned transport vehicle regardless of the weight of the material (the fixed plate can accurately dock with the positioning slot frame), improving the stability and accuracy of transportation. Moreover, compared with the traditional data positioning method, this mechanical positioning method eliminates the need for multiple adjustments to the precise position when the unmanned transport vehicle connects with the pallet. Its positioning efficiency is high and it is not affected by signal interference, ensuring accurate docking between the pallet and the transport vehicle every time.

[0023] Second, the transport equipment used in the construction of this unmanned digital workshop is equipped with a No. 3 telescopic rod, which can drive the No. 2 telescopic rod and the second positioning block to move. When the unmanned transport vehicle moves into or out of the bottom of the pallet, the No. 2 telescopic rod drives the second positioning block to descend completely, and the No. 3 telescopic rod drives the second positioning block to retract, so as to avoid obstruction or collision with the support leg plate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] The first telescopic rod 6, the second telescopic rod 8, and the third telescopic rod 9 in this utility model are all common electric telescopic push rods in the prior art. The fourth telescopic rod 14 can be a powerful electric telescopic rod or a hydraulic push rod (a matching hydraulic system is set inside the unmanned transport vehicle 1). This application will not elaborate further on their models or internal structures.

[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a transport device for the construction of an unmanned digital workshop, including an unmanned transport vehicle 1. The front end of the unmanned transport vehicle 1 is connected to a control box, which integrates various control circuits and software systems. It is responsible for receiving instructions from the workshop control system, such as driving route planning and positioning operation instructions, and converting these instructions into specific action signals, which are then sent to various execution components, such as drive wheels and telescopic rods. The lower end is equipped with multiple steerable drive wheels and auxiliary universal wheels, which give the transport vehicle flexible movement and steering capabilities. The drive wheels, as the main power output components, provide forward and backward power for the unmanned transport vehicle 1, enabling the vehicle to travel in the workshop according to a preset route. The steerable drive wheels can be steering wheels, universal wheels + actuators, etc.

[0034] The unmanned transport vehicle 1 is equipped with a matching pallet 2 on its upper end. Materials are placed on the upper end of the pallet 2. The lower end of the pallet 2 is connected to a support leg plate 10, and the lower end of the support leg plate 10 is connected to a base plate. The lower end of the base plate is connected to a rubber pad with an anti-slip texture. The support leg plate 10 is used to provide space for the unmanned transport vehicle 1 to enter the lower end of the pallet 2. The base plate enhances the load-bearing capacity of the pallet 2, and the rubber pad and its anti-slip texture increase the stability of the pallet 2 when placed on the ground, making the pallet 2 more stable. The upper edge of the pallet 2 is connected to a frame 11, and multiple round holes are opened in the frame 11. The frame 11 can play a certain role in protecting the materials on the pallet 2, preventing the materials from falling off due to vibration or turning during transportation. The round holes can be used to tighten ropes or install other fixing devices to further secure the materials.

[0035] The front and rear ends of the tray 2 are connected to the first slide bar 3, and the two sides of the tray 2 are connected to the second slide bar 4.

[0036] The unmanned transport vehicle 1 is equipped with a positioning mechanism, which includes: two first positioning blocks 5 located at the front and rear ends, two second positioning blocks 7 located at the sides, and a third telescopic rod 9. The lower end of each first positioning block 5 is connected to a first telescopic rod 6, which is vertically positioned and used to adjust the height of the first positioning block 5. The lower end of each second positioning block 7 is connected to a second telescopic rod 8, which is also vertically positioned and used to adjust the height of the second positioning block 7. The sides of the first sliding rod 3 and the second sliding rod 4 are set with smooth inclined surfaces, as are the sides of the first positioning blocks 5 and the second positioning blocks 7. The smooth inclined surface of the first positioning block 5 can interact with the smooth surface of the first sliding rod 3. The smooth inclined surface of the second positioning block 7 interacts with the smooth inclined surface of the second sliding rod 4. The first positioning block 5 rises under the push of the first telescopic rod 6, and its smooth inclined surface contacts the smooth inclined surface of the first sliding rod 3. Due to the interaction force between the inclined surfaces, a horizontal component force is generated. This component force can push the pallet 2 or the unmanned transport vehicle 1 to adjust its position in the front-back direction, thereby completing the front-back positioning. Similarly, the second positioning block 7 rises under the push of the second telescopic rod 8, and its smooth inclined surface interacts with the smooth inclined surface of the second sliding rod 4. The resulting horizontal component force realizes the positioning adjustment of the pallet 2 or the unmanned transport vehicle 1 in the lateral direction.

[0037] The unmanned transport vehicle 1 has support rods 13 connected to its front and rear ends. The first telescopic rod 6 is connected to the side end of the support rod 13 to install and fix the first telescopic rod 6. The third telescopic rod 9 is connected to the body of the unmanned transport vehicle 1. The drive end of the third telescopic rod 9 is connected to the second telescopic rod 8. The third telescopic rod 9 is set horizontally and is used to adjust the horizontal position of the second positioning block 7.

[0038] A positioning slot frame 12 is connected to the lower surface of the pallet 2. The positioning slot frame 12 is located at the center of the pallet 2. Multiple No. 4 telescopic rods 14 are connected to the center of the upper end of the unmanned transport vehicle 1. The driving end of the No. 4 telescopic rod 14 is connected to a fixing plate 15. The fixing plate 15 can be inserted into the positioning slot frame 12 at the lower end of the pallet 2. This can strengthen the connection between the pallet 2 and the unmanned transport vehicle 1, and ensure that the pallet 2 and the unmanned transport vehicle 1 always maintain a stable relative position during transportation. This effectively prevents the pallet 2 from shaking or shifting, and improves the stability and accuracy of transportation.

[0039] Working Principle: During use, the unmanned transport vehicle 1 moves to the lower end of the pallet 2, positioning it approximately at the center of the pallet 2. Then, the positioning mechanism is activated, and the control box issues a command. The first telescopic rod 6 pushes the first positioning block 5 upward, causing its smooth inclined surface to contact the smooth inclined surface of the first sliding rod 3, generating a horizontal thrust. Based on the weight of the material, the pallet 2 is positioned and adjusted in the front-to-back direction. Simultaneously, the third telescopic rod 9 pushes the second telescopic rod 8 and the second positioning block 7 horizontally to the appropriate position. The second telescopic rod 8 then pushes the second positioning block 7 upward, causing its smooth inclined surface to contact the smooth inclined surface of the second sliding rod 4, generating a horizontal thrust. This completes the positioning and adjustment of the pallet 2 in both lateral directions. If the material on the pallet 2 is light, the horizontal thrust generated by the positioning block and sliding rod pushes the pallet 2 to the center of the unmanned transport vehicle 1. If the material is heavy, the thrust generated by the positioning block and sliding rod acts in the opposite direction on the unmanned transport vehicle 1, passively moving it to the center of the pallet 2. This achieves the initial adaptive positioning of the pallet 2 and the unmanned transport vehicle 1.

[0040] After the initial positioning is completed, the control box controls the extension of the No. 4 telescopic rod 14, drives the fixed plate 15 to rise and accurately insert it into the positioning slot frame 12 at the lower end of the pallet 2, and then lifts the pallet 2 so that its side support leg plate 10 is lifted off the ground. Then, according to the route instructions preset by the workshop control system, the control box controls the drive wheel and auxiliary caster to work together to drive the unmanned transport vehicle 1 to transport the materials to the destination according to the designated route.

[0041] When the unmanned transport vehicle 1 arrives at its destination, the control box issues a command, and the fourth telescopic rod 14 retracts, causing the fixing plate 15 to detach from the positioning slot frame 12. The support leg plate 10 of the pallet 2 then contacts the ground. Then, the first telescopic rod 6 and the second telescopic rod 8 retract, causing the first positioning block 5 and the second positioning block 7 to descend and release their contact with the first sliding rod 3 and the second sliding rod 4. Then, the third telescopic rod 9 retracts, causing the second positioning block 7 to retract and reset, thereby avoiding obstruction or collision with the support leg plate 10. At this time, the unmanned transport vehicle 1 can move out from the bottom of the pallet 2.
