Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to an AGV docking system for a manufacturing workshop. Background Art

[0002] In the equipment manufacturing industry, material management is a crucial step in the production process. Materials need to flow between the raw material warehouse, production line, and finished product warehouse during the production process. Currently, material flow within factories is primarily accomplished by manual transportation using spring-loaded trucks. Transported materials need to be neatly stacked on pallets or bins to prevent vibration and damage during transportation. This requires manual and neat stacking of materials, while also requiring manual truck movement to prevent vibration and tipping. This results in low material turnover efficiency, impacting production efficiency. This is particularly true for the production of complex products, where production lines involve multiple processes. Semi-finished materials from each process are transported via trucks, leading to long waiting times and extended production cycles. Utility Model Content

[0018] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are:

[0019] 1. The utility model is an AGV docking system for a manufacturing workshop, which places the material to be transferred directly on the material tray, and uses a pressure sensor to weigh the material carried by the material tray. When the material reaches the specified weight, the material tray can be lifted by the AGV transporter to separate the material tray from the docking platform, and then the material tray is transported to the position to be transferred.

[0035] Please refer to Figure 1An embodiment of the present utility model provides an AGV docking system for a manufacturing workshop, including two docking platforms 1, a material tray 2, a display 3 and an AGV transport vehicle 4.

[0036] Please refer to Figure 2 、 3 and 4, each docking station 1 is fixedly installed at the bottom. The docking station 1 is generally arranged vertically, with the bottom fixed to the ground by anchor bolts, and is located outside the production line. The two docking stations 1 are arranged parallel to each other, and an entry and exit space for the AGV transport vehicle 4 is formed between the two docking stations 1. The shape of the docking station 1 can be flexibly set according to the entry and exit needs of the AGV transport vehicle 4 in the actual application scenario. For example, the shape of the docking station 1 in this embodiment is approximately a rectangular parallelepiped.

[0037] The upper surfaces of the two docking platforms 1 are flush with each other, and the upper surface of each docking platform 1 is provided with a plurality of guide posts 9 and a plurality of pressure sensors 7. In this embodiment, the upper surfaces of the two docking platforms 1 are both horizontally arranged and located on the same horizontal plane.

[0038] The material tray 2 is provided with a plurality of guide holes 12 on its edge. The material tray 2 is supported on each of the pressure sensors 7, and each of the guide holes 12 is slidably mounted on a guide post 9. When the material tray 2 carries material, it presses down on each of the pressure sensors 7. The sum of the pressures detected by each of the pressure sensors 7 is the gravity of the carried material, thereby detecting the weight of the carried material.

[0039] The guide holes 12 and the guide posts 9 are shaped to match each other so that when the guide holes 12 move vertically along the guide posts 9, the material tray 2 can only move in the vertical direction. In some embodiments, a tapered guide head 11 is provided at the upper end of the guide post 9, and the guide holes 12 can move vertically along the guide head 11, so that when the material tray 2 falls onto the two docking platforms 1 before carrying the material, each guide hole 12 can be respectively mounted on each guide head 11, and each guide hole 12 moves downward along the guide head 11 and is accurately mounted on the guide post 9.

[0040] It should be noted that each of the pressure sensors 7 can detect the weight of the material carried in a portion of the material tray 2. Therefore, by comparing the weights of the material carried in each region detected by each pressure sensor 7, the degree of eccentricity of the material carried on the material tray 2 can be determined, thereby adjusting and controlling the degree of eccentricity of the material carried on the material tray 2. In this embodiment, two pressure sensors 7 are provided on the upper surface of each docking station 1. The four pressure sensors 7 of the two docking stations 1 are arranged in a rectangular shape. The material tray 2 is a rectangular plate, and the four corners of the material tray 2 are supported on the four pressure sensors 7. Each pressure sensor 7 can independently detect the weight of a corner of the material tray 2, and based on the weights of the material carried at the four corners of the material tray 2, the degree of eccentricity of the material carried on the material tray 2 can be determined.

[0041] A stop ring 10 is provided in the middle of the guide post 9. The outer diameter of the stop block is larger than the diameter of the guide hole 12. When the guide hole 12 slides downward along the upper end of the guide post 9, the stop ring 10 limits the downward sliding distance of the guide hole 12, thereby limiting the pressure applied by the material tray 2 to the pressure sensor 7, thereby protecting the pressure sensor 7 and preventing damage to the pressure sensor 7 due to excessive external force.

[0042] The display 3 is mounted on one of the docking platforms 1 and is connected to each of the pressure sensors 7 to display the load weight of the material tray 2. The display 3 can be used to observe the current load weight of the material tray 2, thereby determining whether the current load weight of the material tray 2 exceeds a preset weight. The preset weight is determined based on the maximum weight of material that can be transferred each time, to prevent vibration and tipping during transfer due to excessive material.

[0043] In some embodiments, the manufacturing workshop AGV docking system of the present invention further includes an indicator light 6 connected to the display 3. The indicator light 6 illuminates when the load of the material tray 2 exceeds a preset weight. The indicator light 6 can be three-color: when the load of the material tray 2 exceeds the preset weight, the indicator light 6 illuminates one color; when the load of the material tray 2 does not exceed the preset weight, the indicator light 6 illuminates a different color. This allows for intuitive observation of whether the load of the material tray 2 exceeds the preset weight.

[0044] Please refer to Figure 5 The AGV transport vehicle 4 includes a lifting AGV trolley 14 and a carrying platform 15 provided on the lifting AGV trolley 14. The carrying platform 15 is fixedly mounted on the upper portion of the lifting AGV trolley 14. The lifting AGV trolley 14 is a prior art, and various existing AGV trolleys can be flexibly selected according to actual application needs, so a detailed description thereof will not be given.

[0045] The lifting AGV trolley 14 can move between the two docking platforms 1, causing the carrying platform 15 to lift the material tray 2 to separate the material tray 2 from the two docking platforms 1, and then transport the material tray 2 to the transfer location. After the material is removed from the transfer location, the lifting AGV trolley 14 can also transfer the empty material tray 2 back to the two docking platforms 1, allowing the material tray 2 to pass through the guide holes 12 and fall onto the guide pillars 9. The material tray 2 is supported on the pressure sensors 7 for the next material transfer.

[0046] In order to prevent the material tray 2 from slipping when the lifting AGV trolley 14 transports the material tray 2,

[0047] The lower surface of the material tray 2 is provided with a plurality of positioning grooves 13, and the top of the carrying platform 15 is provided with a plurality of positioning blocks 16. The positioning blocks 16 correspond one-to-one with the positioning grooves 13. When the carrying platform 15 lifts the material tray 2, each positioning block 16 is inserted into its corresponding positioning groove 13. The shapes of the positioning grooves 13 and the positioning blocks 16 are adapted to each other, so that the carrying platform 15 can effectively limit the positioning grooves 13 through the positioning blocks 16. Preferably, the positioning grooves 13 are tapered grooves, and the positioning blocks 16 are tapered blocks.

[0048] Please refer to Figure 1 and 6 The present invention further includes an AGV docking system for a manufacturing workshop, further comprising a photoelectric sensor 5 mounted at a predetermined height above the docking platform 1 for detecting the height of the material on the material tray 2. If the detected material height exceeds the predetermined height, the sensor reduces the amount of material or adjusts the material stacking position to prevent the material on the material tray 2 from being stacked too high, which could cause the material to fall during the movement of the AGV transporter 4.

[0049] In some other embodiments, an upwardly extending mounting bracket is provided on the upper portion of the docking platform 1. The mounting bracket includes a base 17, a fixed rod 18, a movable clamp 19, and a mounting plate 20. The base 17 is fixedly mounted on the upper surface of the docking platform 1. The fixed rod 18 is vertically arranged and its lower end is detachably connected to the base 17. The movable clamp 19 clamps the fixed rod 18. The mounting plate 20 is mounted on one side of the movable clamp 19. The photoelectric sensor 5 is mounted on the mounting plate 20. The movable clamp 19 can be adjusted in tension by adjusting the bolt 21, thereby changing its position on the fixed rod 18, thereby adjusting the position of the photoelectric sensor 5 and adjusting the detection height of the photoelectric sensor 5 to facilitate the transport of different materials.

[0050] In addition, in some other embodiments, a manufacturing workshop AGV docking system of the present invention further includes a laser displacement sensor 8, which is disposed on the inner side of the docking platform 1 to detect the horizontal distance from the carrier platform 15 to the docking platform 1. The number of the laser displacement sensors 8 can be multiple, and they are respectively disposed on the opposite side surfaces of the two docking platforms 1 to accurately detect the distance from the loading platform to the two docking platforms 1 on both sides after the lifting AGV trolley 14 enters the two docking platforms 1, thereby determining whether the position of the lifting AGV trolley 14 has shifted, so as to accurately lift the material tray 2.

[0051] The embodiment of the present utility model provides a manufacturing workshop AGV docking system, which can be applied to the transfer of semi-finished products between multiple processes on the equipment manufacturing industry production line. Each process is equipped with a set of the manufacturing workshop AGV docking system. The specific process is as follows:

[0052] First, the semi-finished materials processed in the previous process are placed on the material tray 2, and the display 3 or the indicator light 6 is used to determine whether an appropriate amount of materials are stacked on the material tray 2 to avoid overweight of the materials stacked on the material tray 2, which may cause vibration and tipping during transportation due to excessive materials; the weight data detected by each pressure sensor 7 can also be compared to determine the eccentricity of the materials carried on the material tray 2 to avoid serious eccentricity of the material tray 2 causing eccentric tipping of the materials during transportation; the photoelectric sensor 5 can also be used to detect whether the height of the materials carried on the material tray 2 exceeds a predetermined height to avoid tipping of the materials during transportation due to excessive stacking height of the materials;

[0053] Then, the material tray 2 is lifted up by the lifting AGV trolley 14 through the carrying platform 15, so that the guide holes 12 of the material tray 2 are separated from the guide posts 9 on the two docking platforms 1;

[0054] Next, the lifting AGV trolley 14 transports the material tray 2 to the AGV docking system of the manufacturing workshop of the next process. The lifting AGV trolley 14 enters the predetermined position between the two docking platforms 1 of the AGV docking system of the manufacturing workshop of the next process, aligning each guide hole 12 with each guide column 9 one by one. The lifting AGV trolley 14 then drops the material tray 2 through the carrying platform 15, inserting each guide column 9 into each guide hole 12, and the material tray 2 is supported on each pressure sensor 7;

[0055] Finally, after the material tray 2 carrying the material is removed in the next process, the lifting AGV trolley 14 lifts the empty material tray 2 according to the above method and transports it back to the AGV docking system of the manufacturing workshop of the previous process, and drops the empty material tray 2 according to the above method and supports it on each of the pressure sensors 7 for the next material turnover.
