Description

Technical Field

[0001] This invention relates to the field of AGV conveying technology, and more specifically, to an AGV conveying device. Background Technology

[0002] AGV is an abbreviation for Automated Guided Vehicle. It refers to an unmanned automated vehicle that is equipped with automatic guidance devices such as magnetic strips, tracks or lasers, travels along a planned path, is powered by batteries, and is equipped with safety protection and various auxiliary mechanisms (such as transfer and assembly mechanisms).

[0003] Typically, multiple AGVs, along with a control computer (control console), navigation equipment, charging equipment, and peripheral auxiliary equipment, constitute an AGV system. Its main working principle is that, under the monitoring and task scheduling of the control computer, the AGV can accurately travel along the prescribed path, reach the designated task location, and complete a series of work tasks.

[0004] When the battery power is low, it needs to be charged in time. However, AGVs usually need to be charged in a dedicated charging area by wired charging or static wireless charging. The charging waiting time is long, making it difficult to continuously charge the AGV while it is in motion. This reduces the effective working time of the AGV and thus affects the transportation efficiency of the AGV. Summary of the Invention

By controlling the AGV to move closer to the power track and controlling the charging connection to descend and press against the sliding part, electrical energy is emitted through the transmitting coil on the power receiving part and received through the receiving coil on the charging connection part.

[0042] A power track 2 is installed between the start and end points of the conveying route. By controlling the automatic guided vehicle 1 to move closer to the power track 2 and controlling the charging connection 5 to descend and press against the sliding part 3, electrical energy is emitted through the transmitting coil 16 on the power receiving part and received through the receiving coil 15 on the charging connection 5. The movement of the automatic guided vehicle 1 drives the sliding part 3 to move synchronously, thereby enabling the automatic guided vehicle 1 to charge while working, increasing the effective working time of the automatic guided vehicle 1, and thus improving the conveying efficiency of the automatic guided vehicle 1.

[0046] The top of the support plate 7 is evenly provided with several clearance holes 27; the bottom surface of the clearance holes 27 is provided with through holes 28; the ends of two adjacent inclined guide plates 23 are respectively fixedly connected with an upper cloth strip 29 and a lower cloth strip 30; both the upper cloth strip 29 and the lower cloth strip 30 are equipped with chain teeth 31; two pull tabs 32 are symmetrically fixed on the side of the protective cover 26; the ends of the pull tabs 32 are provided with pull heads 33 that are compatible with the two chain teeth 31; the upper cloth strip 29 and the lower cloth strip 30 are respectively equipped with upper stop and lower stop at both ends.

[0047] A support ring 34 is fixed to the surface of the fixed plate 11; several L-shaped baffles 35 are evenly fixed to the surface of the fixed plate 11; a fixed ring 36 coaxial with the support ring 34 is fixed between the ends of each L-shaped baffle 35; an annular groove 37 is formed between the fixed ring 36 and the support ring 34; the wireless charging plate 22 is slidably disposed in the annular groove 37; a stop rod 38 is slidably disposed through the side of the L-shaped baffle 35; a stop block 39 is fixed to the end of the stop rod 38; a return spring 40 sleeved on the stop rod 38 is fixedly connected between the stop block 39 and the L-shaped support plate 8; an annular cavity 41 is opened on the periphery of the wireless charging plate 22 to engage with the stop rod 38.

[0048] A rotating ring 42 is rotatably mounted on the surface of the base 17; a gear ring 43 is fixed to the outer circumference of the rotating ring 42; a servo motor 44 is fixedly mounted on the surface of the base 17; a gear 45 that meshes with the gear ring 43 is fixed to the output end of the servo motor 44; a guide ring 46 is fixed to the inner circumference of the rotating ring 42; several first curved guide plates 47 are evenly fixed to the inner circumference of the guide ring 46; several sliding grooves 48 are evenly opened on the surface of the base 17; a guide rod 49 is fixed between the inner walls of the sliding grooves 48; an L-shaped abutment 50 that slides with the guide rod 49 is slidably mounted on the inner wall of the sliding grooves 48; a compression spring 51 sleeved on the guide rod 49 is fixedly connected between the L-shaped abutment 50 and the sliding grooves 48; an ear rod 52 is fixed to the surface of the L-shaped abutment 50; a ball head 53 is fixed to the end of the ear rod 52.

[0049] Working principle of this embodiment two:

[0050] A power rail section 2 is installed between the start and end points of the conveying route. Specifically, the fixing frame 6 is placed flat on the conveying route, and the fastening bolts are passed through the through hole 28 and fixed to the surface of the conveying route. Then, two sets of snap-fit ​​plates 9 are inserted into the corresponding adjacent two L-shaped support plates 8, and the snap-fit ​​plates 9 are fixed to the L-shaped support plates 8 by fastening screws. One end of the conductive rail 10 on the two sets of snap-fit ​​plates 9 is connected to the positive and negative terminals of the power supply, respectively.

[0051] The insulating wheel 25 on the sliding part 3 can move freely on the corresponding inclined guide plate 23. The conductive rail 10 contacts the corresponding I-shaped conductive wheel 13 to conduct electricity. It is electrically connected to the wireless charging plate 22 through the conductive post 12 and the cable, so that the transmitting coil 16 can transmit electrical energy. The wireless charging conversion plate 19 is electrically connected to the battery pack 21. The receiving coil 15 is used to receive the electrical energy transmitted by the transmitting coil 16, thereby completing the wireless charging of the battery pack 21.

[0052] The charging effect is optimal when the receiving coil 15 and the transmitting coil 16 are coaxially aligned. However, there is a possibility of deviation during the transport process of the automated guided vehicle 1, making it difficult to guarantee that the automated guided vehicle 1 can automatically and accurately position itself each time, so that the receiving coil 15 and the transmitting coil 16 are coaxially aligned. The following discusses how to solve the above problems.

[0053] In the initial state, the return spring 40 is in the normal state (neither contracted nor extended), each set of abutment rods 38 extends into the annular cavity 41, and their ends are in contact with the inner circumferential side of the annular cavity 41. The wireless charging plate 22 and the transmitting coil 16 are coaxially arranged with the fixing ring 36. Under the elastic force of the compression spring 51, the L-shaped abutment plate 50 is driven to press against the inner wall of the slide groove 48.

[0054] First, control the automatic guided vehicle 1 to move close to the power track section 2 until the charging connection section 5 is placed above the sliding section 3. Then, control the start of the electric push rod to drive the charging connection section 5 to slide down along the inner wall of the mounting cavity 4 until the base 17 presses against the surface of the L-shaped baffle 35. At this time, the receiving coil 15 and the fixed ring 36 are not on the same axis, that is, the receiving coil 15 and the transmitting coil 16 are not on the same axis.

[0055] To increase the friction between the base 17 and the L-shaped baffle 35, anti-slip textures can be made on the bottom surface of the base 17 and the surface of the L-shaped baffle 35. Of course, any technical solution that can increase the friction between the two is acceptable.

[0056] The servo motor 44 is controlled to drive the gear 45 to rotate slowly, thereby driving the gear ring 43 and the rotating ring 42 to rotate slowly. This causes the first curved guide plate 47 to rotate slowly and contact the corresponding ball head 53, pressing the ball head 53. This causes the L-shaped abutment 50 to slide along the corresponding slide groove 48 towards the receiving coil 15, and the corresponding compression spring 51 is compressed. Since the receiving coil 15 and the fixed ring 36 are not on the same axis, the distance between each set of L-shaped abutments 50 and the wireless charging plate 22 is not the same. The L-shaped abutment closest to the wireless charging plate 22... The plate 50 first contacts and pushes, causing the wireless charging plate 22 to move along the annular groove 37. Each group of L-shaped abutments 50 pushes the wireless charging plate 22 to move in the annular groove 37 in turn. When the highest point of the first curved guide plate 47 contacts the ball head 53, the servo motor 44 is stopped. At this time, the final positions of each group of L-shaped abutments 50 are consistent, so that the wireless charging plate 22 and the base 17 are coaxially set, that is, the transmitting coil 16 and the receiving coil 15 are coaxially set, completing the automatic coaxial positioning of the transmitting coil 16 and the receiving coil 15.

[0057] The automated guided vehicle 1 is controlled to travel along a designated route. The charging connection part 5 drives the sliding part 3 to slide synchronously along the power track part 2, so that the automated guided vehicle 1 can be charged while transporting, which increases the effective working time of the automated guided vehicle 1 and thus improves the transport efficiency of the automated guided vehicle 1. During the transport process, the automated guided vehicle 1 drives the two pull plates 32 to move synchronously, so as to realize the synchronous opening and closing of the upper cloth belt 29 and the lower cloth belt 30. This ensures that the conductive rail 10 inside the fixed frame 6 is kept insulated from the outside world during the transport and charging process of the automated guided vehicle 1, thereby improving safety performance.

[0058] Example 3, please refer to Figure 1-16This third embodiment is an improvement on the second embodiment as follows: Specifically, a U-shaped frame 54 is fixedly installed on the surface of the automated guided vehicle 1; an L-shaped support plate 55 is slidably arranged on the U-shaped frame 54; forks 56 are symmetrically fixed on the side of the L-shaped support plate 55; limit plates 57 are symmetrically fixed on the side of the U-shaped frame 54; a mounting plate 58 is fixed on the side of the U-shaped frame 54; a controller 59 and a drive motor 60 are fixedly installed on the surface of the mounting plate 58; a lead screw 61 is fixed at the output end of the drive motor 60; and an extension plate 62 that is threadedly engaged with the lead screw 61 is fixed on the side of the L-shaped support plate 55.

[0059] Angle steel 63 is symmetrically fixed to the surface of the automated guided vehicle 1; a guide plate 64 is slidably arranged through the side of the angle steel 63; a guide ball 65 is fixed to one end of the guide plate 64; a rotating rod 66 is rotatably arranged on the surface of the automated guided vehicle 1; an annular plate 67 is fixed to the circumference of the rotating rod 66; a second curved guide plate 68 is symmetrically fixed to the circumference of the annular plate 67; a mounting base 69 is fixed to the other end of the guide plate 64; a universal wheel 70 is installed on the bottom surface of the mounting base 69; a connecting spring 75 sleeved on the guide plate 64 is fixedly connected between the mounting base 69 and the angle steel 63; an ear plate 71 is fixed to the side of the extension plate 62; a fixing ball 72 is fixed to the end of the ear plate 71; vertical guide grooves 73 and spiral grooves 74, which are adapted to the fixing ball 72, are sequentially opened from top to bottom on the circumference of the rotating rod 66; the vertical guide grooves 73 and spiral grooves 74 are interconnected.

[0060] Working principle of this embodiment three:

[0061] During the transport of the automated guided vehicle 1, the L-shaped pallet 55 is placed above the limiting plate 57. At this time, the fixed ball 72 is placed inside the spiral groove 74, and the guide ball 65 is pressed against the side of the annular plate 67 under the elastic force of the connecting spring 75 (the connecting spring 75 is always in a stretched state). At this time, the two sets of universal wheels 70 approach the automated guided vehicle 1.

[0062] When the automated guided vehicle 1 moves to the designated position, the start drive motor 60 is controlled to rotate the lead screw 61, thereby causing the extension plate 62 and the L-shaped pallet 55 to slide upward along the U-shaped frame 54, lifting the material onto the external transfer platform for unloading. Because the goods are lifted, the center of gravity of the entire device increases, reducing the stability of unloading. During this process, the automated guided vehicle 1 stops, and the fixed ball 72 slides from the spiral groove 74 into the vertical guide groove 73. As the fixed ball 72 slides in the spiral groove 74, it drives the rotating rod 66 to rotate. The second curved guide plate 68 rotates 90°, thereby causing the annular plate 67 to rotate 90°. The second curved guide plate 68 rotates and presses the corresponding guide ball 65, causing the guide plate 64 to slide along the angle steel 63 in a direction away from the annular plate 67. This causes the two casters 70 to move away from the automatic guided vehicle 1, increasing the support area of ​​the automatic guided vehicle 1 and improving the stability of unloading the automatic guided vehicle 1. When the fixed ball 72 slides in the vertical guide groove 73, the rotating rod 66 does not rotate, that is, the subsequent lifting casters 70 of the goods have reached the final unfolded state and will not move accordingly.
