The docking mechanism is arranged on the fixed flower basket mechanism, the movable flower basket mechanism is connected to the automatic trolley, the docking mechanism includes a docking rack, a transfer drive mechanism and a docking device, the docking rack is connected to the fixed flower basket mechanism, and a docking device is arranged below the docking rack. The above structure, by setting the docking device, makes the connection between the fixed flower basket mechanism and the movable flower basket mechanism firm, and the movable flower basket mechanism is not easy to be separated from the fixed flower basket mechanism, so that when the movable flower basket mechanism is connected to the fixed flower basket mechanism, the photovoltaic flower basket can be stably transported. The defects and shortcomings of the transport system are: it forms a physical connection between the fixed flower basket mechanism and the movable flower basket mechanism through the docking device, so that when the automatic trolley and the docking mechanism are docked, a collision will occur, and after long-term use, the docking device will be worn, which will lead to a decrease in docking accuracy, docking errors, and stagnation in the circulation and transportation of photovoltaic flower baskets.

[0042] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific implementation methods. Figure 1 and Figure 2 It should be further explained that the flower basket cache docking platform 2 is fixed, the movement direction of the conveyor line on the flower basket cache docking platform 2 is the front-to-back direction, and during docking, the automatic guided vehicle 1 is located directly behind the flower basket cache docking platform 2.

[0043] Reference Figure 1 and Figure 2 This embodiment provides a flower basket transportation device for a photovoltaic plant, including an automatic guided vehicle 1 and a flower basket cache docking platform 2.

[0044] The flower basket cache docking station 2 includes a docking station body 21, the docking station body 21 has a first cache layer 22 and a second cache layer 23, a reference object mounting plate 28 is arranged at the lower part of the rear side of the docking station body 21, a reference object 29 is respectively installed on the left and right sides of the reference object mounting plate 28, and a first reflective plate 25 is arranged at the upper part of the first cache layer 22;

[0045] The automatic guided vehicle 1 includes a vehicle body 11, on which a first transport layer 12 and a second transport layer 13 are provided, a first universal wheel is provided at the bottom of the vehicle body 11, a laser sensor 17 is provided at the lower part of the front side of the vehicle body 11, and a first photoelectric sensor 15 is provided at the lower part of the second transport layer 13, and the first photoelectric sensor 15 emits a first light signal forward and downward;

[0046] The laser sensor 17 and the two reference objects are configured such that when the AGV 1 is centered with the basket buffer docking station 2, the distances between the laser sensor 17 and the two reference objects 29 are the same, that is, the laser sensor 17 cooperates with the two reference objects 29 to detect that the AGV 1 is centered with the basket buffer docking station 2. The first photoelectric sensor 15 and the first reflector 25 are configured such that when the AGV 1 moves to a predetermined docking position, the first reflector 25 receives a first light signal emitted by the first photoelectric sensor 15.

[0047] Furthermore, a sensor mounting bracket 26 is provided at the lower part of the second buffer layer 23, and a second photoelectric sensor 27 is installed on the sensor mounting bracket 26, and the second photoelectric sensor 27 emits a second light signal to the rear and downward direction; a second reflector 16 is provided at the upper part of the first transport layer 12, and the second reflector 16 and the second photoelectric sensor 27 are configured such that when the automatic guided vehicle 1 moves to the predetermined docking position, the second reflector 16 receives the second light signal emitted by the second photoelectric sensor 27. The purpose of providing the second photoelectric sensor 27 and the second reflector 16 is to improve the docking accuracy and detect whether the flower basket transport device of this embodiment has docked incorrectly.

[0048] In this embodiment, two vehicle-mounted conveyor lines 14 are respectively installed on the first transport layer 12 and the second transport layer 13, and two fixed conveyor lines 24 are respectively installed on the first cache layer 22 and the second cache layer 23. When the automatic guided vehicle 1 and the flower basket cache docking station 2 are precisely docked, the vehicle-mounted conveyor line 14 is connected with the fixed conveyor line 24 in a one-to-one correspondence, and the vehicle-mounted conveyor line 14 moves the photovoltaic flower basket to the fixed conveyor line 24 to realize the loading of the photovoltaic flower basket cache docking station 2; or the fixed conveyor line 24 moves the photovoltaic flower basket to the vehicle-mounted conveyor line 14 to realize the unloading of the flower basket cache docking station 2.

[0049] Furthermore, a charging port 18 is provided at the bottom of the automated guided vehicle 1 for connecting to an external power source.

[0050] The docking process of the flower basket transportation equipment used in the photovoltaic plant of this embodiment is as follows: first, the automatic guided vehicle 1 scans the two reference objects 29 on the flower basket cache docking platform 2 through the laser sensor 17, that is, the laser sensor 17 emits a laser, which is irradiated on the two reference objects 29 at the bottom of the flower basket cache docking platform 2. The reference object 29 reflects the laser back to the laser sensor 17. The laser sensor 17 calculates the relative distance based on the time difference of the characteristic laser signals reflected by the two reference objects 29, and adjusts the position and orientation of the automatic guided vehicle 1 based on the distance between the two reference objects 29 and the center of the laser sensor 17, so that the distance between the laser sensor 17 and the two reference objects 29 is the same, thereby realizing the centering positioning of the automatic guided vehicle 1 and the flower basket cache docking platform 2. Secondly, when the AGV 1 moves to the predetermined docking position, the first photoelectric sensor 15 on the AGV 1 emits a first beam signal to illuminate the first reflector 25 on the basket buffer docking station 2, and the second photoelectric sensor 27 on the basket buffer docking station 2 emits a second beam signal to illuminate the second reflector 16 on the AGV 1, and the AGV 1 and the basket buffer docking station 2 generate a transport execution signal. Finally, the two run the conveyor line together to realize the transfer of photovoltaic basket materials.

[0051] There are cleanliness requirements during the production process of the photovoltaic plant. In order to prevent impurities from mixing into the photovoltaic flower baskets during transportation, the left side, right side and rear side of the automatic guided vehicle 1 of this embodiment are closed, and the front side is open; the left side and right side of the flower basket cache docking station 2 are closed, and the front side and rear side are open.

[0052] The current photovoltaic plants are huge in scale, with the number of automatic guided vehicles 1 in a single plant area ranging from 200 to 400, while the number of flower basket cache docking stations 2 is several times that of the automatic guided vehicles 1. After the automatic guided vehicle 1 and the flower basket cache docking station 2 of this embodiment adopt contactless laser positioning, the following problems are introduced: laser positioning has high requirements on the installation position of the photoelectric sensor and the reflector, but the ground flatness of the photovoltaic plant is poor and inconsistent, and hundreds of flower basket cache docking stations 2 need to be manually debugged after entering the photovoltaic plant, that is, the installation position of the first reflector 25, the second photoelectric sensor 27 and the reference object 29 on the flower basket cache docking station 2 and the height of the fixed conveyor line 25 are debugged to match the automatic guided vehicle 1, but manual adjustment not only has large adjustment errors, but also seriously wastes human resources and time resources.

[0053] To solve the above problems, refer to Figure 3 , Figure 4 and Figure 5 This embodiment also provides a tooling vehicle for performing consistency modification on the above-mentioned flower basket cache docking station 2. It should be noted that "consistency modification" means that all flower basket cache docking stations 2 in the photovoltaic plant are modified by the tooling vehicle so that the height of the fixed conveyor line 24, the installation position of the reference object 29, the installation position of the first reflector 25, and the installation position and installation angle of the second photoelectric sensor 27 on all flower basket cache docking stations 2 are consistent, thereby ensuring that the automatic guided transport vehicle 1 can be smoothly docked with each flower basket cache docking station 2, and realizing the circulation and transportation of photovoltaic flower baskets in the photovoltaic plant production line.

[0054] The tooling vehicle 3 includes a vehicle frame body 301, the vehicle frame body 301 has a first reference layer 302 and a second reference layer 303, the heights of the first reference layer 302 and the second reference layer 303 are respectively the same as the heights of the first transport layer 12 and the second transport layer 13; a third photoelectric sensor 309 is installed at the bottom of the second reference layer 303, and the installation position and installation angle of the third photoelectric sensor 309 on the second reference layer 303 are the same as the installation position and installation angle of the first photoelectric sensor 15 on the second transport layer 13;

[0055] A reference calibration plate 311 is slidably mounted on the lower portion of the front side of the frame body 301 along the front-to-back direction, the center plane of the reference calibration plate 311 coincides with the center plane of the frame body 301, and openings 314 are symmetrically arranged on both sides of the reference calibration plate 311;

[0056] When the tooling vehicle 3 is docked with the flower basket cache docking station 2, the third photoelectric sensor 309 emits a third light signal forward and downward to locate the installation position of the first reflector 25, and the reference object calibration plate 311 moves forward so that the two openings 314 locate the installation positions of the two reference objects 29 on the reference object mounting plate 28.

[0057] Furthermore, two linear bearings 313 are fixedly installed on the front side of the vehicle frame body 301, and a guide shaft 312 is slidably arranged inside each of the two linear bearings 313, and a reference calibration plate 311 is connected to one end of the guide shaft 312 away from the vehicle frame body 301. When the guide shaft 312 extends forward under the limit of the linear bearing 313, the reference calibration plate 311 abuts against the reference mounting plate 28 of the flower basket cache docking station 2, and the openings 314 on both sides of the reference calibration plate 311 mark the installation position of the reference 29, and the two sides of the reference 29 are aligned with the two right-angled sides of the opening 314, thereby achieving symmetry relative to the center plane of the flower basket cache docking station 2.

[0058] Furthermore, a reference reflector 310 is installed on the top of the first reference layer 302. The installation position of the reference reflector 310 on the first reference layer 302 is the same as the installation position of the second reflector 16 on the first transport layer 12. When the tooling vehicle 3 docks with the flower basket cache docking station 2, the reference reflector 310 locates the front and rear position of the sensor mounting bracket 26 and the installation angle of the second photoelectric sensor 27. In other words, according to the position of the reference reflector 310, the front and rear position of the sensor mounting bracket 26 and the installation angle of the second photoelectric sensor 27 are adjusted, and finally the second light signal emitted by the second photoelectric sensor 27 is irradiated on the reference reflector 310.

[0059] In this embodiment, a plurality of second universal wheels 315 are provided at the bottom of the vehicle frame body 301, and the number and arrangement position of the second universal wheels 315 on the vehicle frame body 301 are the same as the number and arrangement position of the first universal wheels on the transport vehicle body 11. The purpose of such arrangement is to converge the consistency error of multiple vehicles parking at a fixed point when the ground is uneven. Preferably, the second universal wheel 315 is a brake universal wheel, which can perform fixed-point parking for the vehicle frame body 301 so that the tooling vehicle 3 can transform the flower basket cache docking station 2.

[0060] In this embodiment, two tooling plate conveyor lines are respectively arranged on the first reference layer 302 and the second reference layer 303 of the tooling vehicle 3, each tooling plate conveyor line includes two parallel tooling sliding groove plates 304 and guide bars 305 erected on opposite sides of the two tooling sliding groove plates 304, and tooling plates 306 for simulating photovoltaic flower baskets are placed on the tooling sliding groove plates 304. When the tooling vehicle 3 is docked with the flower basket cache docking station 2, the front end of the tooling plate 306 can slide one by one along the tooling sliding groove plates 304 to the fixed conveyor line 24, thereby assisting in positioning and correcting the height of each fixed conveyor line 24.

[0061] The working principle of the tooling vehicle used for consistency modification of the photovoltaic industry docking station of the present embodiment is as follows: since the heights of the first reference layer 302 and the second reference layer 303 of the tooling vehicle 3 of the present embodiment are constant and of high precision, when multiple flower basket cache docking stations 2 enter the photovoltaic plant, the tooling vehicle 3 is used to modify the multiple flower basket cache docking stations 2 one by one, so that the fixed conveyor lines 24 on the first cache layer 22 and the second cache layer 23 on the multiple flower basket cache docking stations 2 are of the same height, and when docking with the automatic guided vehicle 1 later, the photovoltaic flower baskets are fed or unloaded smoothly. Specifically, the tooling plate 306 on the tooling vehicle 3 slides horizontally along the tooling sliding groove plate 304 one by one to the fixed conveyor line 24 of the flower basket cache docking station 2, and its front end assists in positioning the height of the fixed conveyor line 24, and then adjusts the height of each fixed conveyor line 24 one by one, and finally makes the height of the fixed conveyor lines 24 on the multiple flower basket cache docking stations 2 consistent, which is convenient for subsequent smooth docking.

[0062] See also Figure 6 , Figure 7 and Figure 8 A first long slot 307 is provided on the front side of the tooling plate 306, and a concave area 308 is provided on the back side of the tooling plate 306. The depths of the first slot 307 and the concave area 308 are 1.4mm-3.2mm; a second slot is provided on the tooling sliding slot plate 304 corresponding to the first slot 307. When the tooling plate 306 faces downward and is placed on the tooling sliding slot plate 304, the first slot 307 cooperates with the second slot, so that the front side of the tooling plate 306 is 1.4mm-3.2mm lower than the upper surface of the tooling sliding slot plate 304; when the tooling plate 306 faces downward and is placed on the tooling sliding slot plate 304, the height of the back side of the tooling plate 306 at the concave area 308 is 1.4mm-3.2mm higher than the upper surface of the tooling sliding slot plate 304.

[0063] The placement of the tooling plate 306 in this embodiment is as follows:

[0064] When the first buffer layer 22 of the docking station body 21 is feeding and the second buffer layer 23 is discharging, the front side of the tooling plate 306 on the first reference layer 302 faces downward, so that the positioning height of the fixed conveyor line 24 on the first buffer layer 22 is lower than the height of the tooling sliding slot plate 304 on the first reference layer 302; the back side of the tooling plate 306 on the second reference layer 303 faces downward, so that the positioning height of the fixed conveyor line 24 on the second buffer layer 23 is higher than the height of the tooling sliding slot plate 304 on the second reference layer 303;

[0065] When the second cache layer 23 of the transfer platform body 21 is feeding and the first cache layer 22 is discharging, the tooling plate 306 on the second reference layer 303 is placed with the front side facing downward, so that the positioning height of the fixed conveyor line 24 on the second cache layer 23 is lower than the height of the tooling sliding slot plate 304 on the second reference layer 303; the tooling plate 306 on the first reference layer 302 is placed with the back side facing downward, so that the positioning height of the fixed conveyor line 24 on the first cache layer 22 is higher than the height of the tooling sliding slot plate 304 on the first reference layer 302.

[0066] The tooling plate 306 of this embodiment adopts the above-mentioned structure and corresponding placement method for the purpose of allowing the photovoltaic flower basket to enter the flower basket cache docking station 2, or move out of the flower basket cache docking station 2, always moving from a high place to a low place, thereby ensuring the stability and smoothness of loading and unloading of the photovoltaic flower basket.

[0067] The tooling vehicle 3 of this embodiment has the following advantages: 1. The tooling plate conveyor line position and height, photoelectric sensor position and angle, etc. of the tooling vehicle 3 are the same as those of the automatic guided vehicle 1, and the accuracy is higher. 2. The tooling vehicle 3 is used to transform the flower basket cache docking station 2 quickly and efficiently, saving manpower. 3. The tooling vehicle 3 can accurately locate the specific position of the photoelectric docking between the automatic guided vehicle 1 and the flower basket cache docking station 2 to achieve visibility. 4. The tooling vehicle 3 can be moved and fixed quickly. 5. The tooling vehicle 3 can quickly match the fixed conveyor line 24 of the flower basket cache docking station 2, and adjust the height for consistency according to whether the fixed conveyor line 24 is feeding or discharging. 6. The simulated material tooling plate 306 on the tooling vehicle 3 can be used on both sides, that is, the front side is placed downwards corresponding to the material flow direction of the automatic guided vehicle 1 → the flower basket cache docking platform 2, and the back side is placed downwards corresponding to the material flow direction of the flower basket cache docking platform 2 → the automatic guided vehicle 1, finally achieving a docking height difference of 1.4mm-3.2mm to ensure smooth material movement.
