[0034] At present, the assembly process of wind turbines has mostly changed from fixed-point assembly to pulsating production. Pulsating flow is mainly for rail transfer or omnidirectional vehicle with tooling for transfer. The rail-type pulsating assembly line has problems such as insufficient pressure bearing, high failure rate, and hindering material distribution; the omnidirectional vehicle processing and assembly transfer method has problems such as difficulty in the vehicle body entering the tooling, safety risks in the walking process, and difficulty in judging the position of the vehicle body. Therefore, a transfer method is urgently needed to improve the above problems.
[0035] In view of this, the utility model provides a fan pulsation assembly production line transfer device, Figures 1 to 7 The utility model provides an embodiment of a fan pulsation assembly production line transfer device, which will be described below in conjunction with specific drawings.
[0036] See also Figures 1 to 7 The fan pulsation assembly production line is provided with a plurality of assembly stations, and a guide track is provided between the plurality of assembly stations. The fan pulsation assembly production line transfer device 100 comprises a load-bearing tool 1 and a transfer trolley 2. The load-bearing tool 1 comprises a load-bearing platform 11 extending in the front-back direction and a plurality of legs 12 located at the bottom of the load-bearing platform 11. The plurality of legs 12 are located on the left and right sides of the load-bearing platform 11 to define an avoidance space 13 located in the middle below the load-bearing platform 11 and extending in the front-back direction; the transfer trolley 2 comprises a load-bearing tool 1 and a transfer trolley 2. The trolley 2 is used to move along the guide track, and a lifting structure is provided on the top of the transfer trolley 2, so that the transfer trolley 2 can extend into the avoidance space 13 in the front and rear directions to lift the carrying tool 1 to drive the carrying tool 1 to move; wherein, a positioning sensing device is provided between the transfer trolley 2 and the assembly station to position the transfer trolley 2 at the assembly station; a distance sensing device is provided between the transfer trolley 2 and the carrying tool 1 to center the transfer trolley 2 in the avoidance space 13.
[0037] In the technical solution of the utility model, the carrying tool 1 is mainly used to carry the equipment to be assembled. The carrying tool 1 is arranged as a combination structure of the carrying platform 11 and the supporting legs 12. While ensuring the carrying stability, an avoidance space 13 for accommodating the transfer cart 2 is reserved, so that the transfer cart 2 can be moved into the avoidance space 13, and the carrying tool 1 is connected to the equipment to be assembled and lifted up through the jacking structure on the transfer cart 2, so that the equipment to be assembled can be driven by the transfer cart 2 to implement pulsating production, thereby meeting functional requirements. Specifically, the transfer cart 2 needs to move accurately between the multiple assembly stations and stay accurately at the assembly stations to meet the stability of the fan pulsation assembly production line transfer device 100. Therefore, the present application sets the guide track between the multiple assembly stations to guide the transfer cart 2 to move accurately between the multiple assembly stations, and the positioning sensing device is set between the assembly station and the transfer cart 2, so that when the transfer cart 2 moves along the guide track to the assembly station, it is sensed and positioned by the positioning sensing device to ensure the accurate stop of the transfer cart 2. In addition, the distance sensing device is also set between the transfer cart 2 and the carrying tool 1 to ensure that the transfer cart 2 is relatively centered with the carrying tool 1, on the one hand to avoid collision with the carrying tool 1 when the transfer cart 2 extends into the avoidance space 13, and on the other hand to avoid instability of the equipment to be assembled carried by the carrying tool 1 when the transfer cart 2 moves, so as to reduce the risk of transportation. In summary, the present application proposes a fan pulsation assembly production line transfer device 100 with high product transfer accuracy and strong transfer stability.
[0038] Specifically, the distance sensing device includes a distance sensing component and a positioning sensing component. The distance sensing component is arranged between the left and right sides of the transfer trolley 2 and the load-bearing tooling 1 to adjust the left-right distance between the transfer trolley 2 and the load-bearing tooling 1; the positioning sensing component is arranged between the transfer trolley 2 and the load-bearing tooling 1 to adjust the front-back and upward position of the transfer trolley 2 relative to the load-bearing tooling 1. The transfer trolley 2 extends into the avoidance space 13 from the front and rear directions of the carrying tooling 1. On the one hand, it is necessary to ensure that the transfer trolley 2 does not collide with the support legs 12 during the process of the transfer trolley 2 extending into the avoidance space 13, and on the other hand, it is necessary to ensure that the distance between the transfer trolley 2 and the support legs 12 on its left and right sides is equal, that is, it is centered in the left and right directions. Therefore, the present application sets the distance sensing component between the left and right sides of the transfer trolley 2 and the carrying tooling 1 to sense the distance between it and the support legs 12 in real time during the process of the transfer trolley 2 extending into the avoidance space 13, to ensure the stability of the activity process, and to meet the above requirements; and the size of the transfer trolley 2 extending into the avoidance space 13 only needs to ensure the accuracy of the final stopping position of the transfer trolley 2, so it can be sensed and positioned by the positioning sensing component, which is simple, practical and low in cost. By presetting the sensing position of the positioning sensing component, the relative position of the transfer trolley 2 and the carrying tooling 1 in the front and back and upward directions can be accurately positioned to meet the centering requirement. In this way, the distance sensing device is configured as the distance sensing component and the positioning sensing component, which has good effect, low cost and practicability.

At the same time, in order to ensure the stability and accuracy of the detection, the present application also provides baffles 14 on the left and right sides of the avoidance space 13 corresponding to the position of the acoustic wave sensor, so that the transfer cart 2 can perform left and right distance detection and adjustment throughout the activity of extending into the avoidance space 13, ensure the stability of its activity process, avoid collision, and improve the left and right positioning accuracy of the transfer cart 2. It can be understood that the number of acoustic wave sensors can be set without limitation, and they can be set on the left and right sides of the transfer cart 2, and multiple acoustic wave sensors can be set at intervals along the front and rear directions. In this embodiment, eight acoustic wave sensors are provided to be arranged on the left and right sides of the transfer cart 2.
[0040] In addition, the positioning sensing component includes a visual sensor provided on one of the transfer cart 2 and the carrying tool 1, and a visual identification component provided on the other.

In order to ensure the recognition accuracy of the visual sensor, the visual identification component is set as a QR code in this embodiment, so that the transfer cart 2 is stopped only after the visual sensor recognizes the above QR code, so as to avoid the external environment affecting the sensing of the visual sensor.
[0041] In addition, a magnetic track is buried between the multiple assembly stations to form the guide track, and a magnetic sensing device is correspondingly provided on the transfer cart 2. The guide track can be provided in various forms, including but not limited to an optical guide track, and an optical recognition device can be provided on the transfer cart 2.

Specifically, the specific laying form of the magnetic track is not limited here, and it can be a buried magnetic strip, a magnetic tape, and a pasted magnetic sticker, etc., which can ensure the stability of the use of the magnetic track, the service life, and the accurate recognition of the magnetic sensing device.
[0042] In addition, the positioning sensing device includes a wireless sensing component arranged between the transfer trolley 2 and the assembly station. The positioning sensing device is mainly used to accurately position the transfer trolley 2 at the assembly station for easy assembly, so the positioning sensing device can be a mechanical activity trigger sensing device, a physical contact sensing device, and a remote wireless sensing device, which can achieve the above functions and is not limited here. In this embodiment, the positioning sensing device is set as the wireless sensing component, which does not require contact sensing, has a long service life and is more convenient for spatial layout.
[0043] Specifically, the wireless sensing component includes an identification chip arranged on the transfer cart 2 and a wireless radio frequency identification device arranged at the assembly station. The wireless sensing component can also be set in a variety of ways, including but not limited to laser sensing, visual sensing, etc. In this embodiment, it is set to wireless radio frequency identification (RFID, Radio Frequency Identification), that is, the wireless radio frequency identification device is set at the assembly station, and the identification chip is set on the transfer cart 2 at the same time. On the one hand, it can be used as the positioning sensing device to accurately position the transfer cart 2 at the assembly station, and on the other hand, it can be used as a production information record of the equipment to be assembled to facilitate equipment tracking.
[0044] In addition, a positioning structure is provided on the carrying platform 11, and the positioning structure is used to position the equipment to be assembled carried by the carrying tool 1. The carrying platform 11 is used to carry the equipment to be assembled, and in order to ensure the stability of the placement of the equipment to be assembled, it is generally necessary to position and fix the equipment to be assembled, so the positioning structure is provided on the carrying platform 11 in this application to achieve the above function.
