This method cannot quickly achieve the transfer of the engine body from one process to the next, and the overall efficiency is low. It also requires the cooperation of the corresponding power device, which is relatively complex in structure and cannot achieve precise positioning, and can only transfer the pallet.

DETAILED DESCRIPTION

[0024] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] The present invention will be described in detail below with reference to the accompanying drawings. This embodiment discloses a tray transmission system for a hoist. Figure 1As shown, it includes a tray base 2, a first tray body 3, a second tray body 19, and a transmission mechanism 12; the first tray body 3 is provided at one end of the tray base 2, and the second tray body 19 is provided at the other end; the transmission mechanism 12 is connected to one end of the first active roller 13, and the first active roller 13 is provided in the first tray body 3; the other end of the first active roller 13 is connected to one end of the rotating shaft 14, and the other end of the rotating shaft 14 is connected to one end of the second active roller 15, and the second active roller 15 is in the second tray body 19; the transmission mechanism 12 is configured to transmit power to the first active roller 13, and the first active roller 13 is rotated under the force and drives the rotating shaft 14 to rotate, thereby driving the second active roller 15 to rotate.

[0026] The transmission mechanism 12 includes a housing 20, a driving sprocket 16, a driven sprocket 17, and a transmission chain 18. One end of the driving sprocket 16 is connected to the output end of the tray servo motor 4, and the other end of the driving sprocket 16 is connected to one end of the first driving roller 13. A plurality of driven sprockets 17 are provided at both ends of the driving sprocket 16. The driven sprockets 17 and the driving sprocket 16 are connected via a transmission chain 18. One end of the driven sprocket 17 is connected to the driven roller 5, which is located within the first tray body 3. The tray servo motor 4 is mounted on the housing 20 of the transmission mechanism 12, and the driving sprocket 16, the driven sprocket 17, and the transmission chain 18 are located within the housing 20. The tray servo motor 4 is a motor that can precisely control its speed and position. It achieves high-precision positioning and speed adjustment through a feedback control system. In the elevator transmission tray, it is used to drive the roller and adjust the tray height.

[0027] like Figure 2 As shown, when in use, the tray servo motor 4 starts to drive the driving sprocket 16 to rotate, and then the transmission chain 18 drives the driven sprocket 17 to rotate, thereby rotating the first active roller 13 and the driven rollers 5 arranged at both ends of the first active roller 13, the first active roller 13 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the second active roller 15 to rotate, the second active roller 15 drives the corresponding driving sprocket 16 to rotate, the driving sprocket 16 drives the driven sprocket 17 to rotate through the transmission chain 18, thereby rotating the driven rollers 5 arranged at both ends of the second active roller 15, that is, all rollers rotate simultaneously to transport the machine body.

[0028] That is, the machine body is driven by the cooperation of the roller and the pallet servo motor 4. The machine body is transported from the conveyor belt of the previous process to the limit guide rail 6. After precise positioning, the pallet body is adjusted in height by the hoist servo motor 9 driving the ball screw 8. The laser displacement sensor 10 installed on the side panel of the hoist is used to accurately monitor the height of the pallet body 3 to meet the production line's requirements for the machine body height. After processing is completed, the pallet servo motor 4 drives the roller to transfer the machine body smoothly and accurately to the conveyor belt of the downstream process. Through the coordinated action of the roller, the limit guide rail 6 and the pallet servo motor 4, the excess degrees of freedom of the machine body are effectively limited, and the stability and transmission efficiency of the system are improved.

[0029] A plurality of square holes are provided at intervals on the upper portions of the first and second tray bodies 3, 19. The first active roller 13, the second active roller 15, and the driven roller 5 are positioned at the positions of the square holes. The upper portions of the rollers protrude from the square holes, allowing the upper portions of the rollers to contact the lower surface of the machine body, thereby achieving conveyance of the machine body.

[0030] A limit rail 6 is installed on the upper portion of the first and second pallet bodies 3, 19, located at one end of the square hole. A proximity switch 7 is installed at one end of the first and second pallet bodies 3, 19. The limit rail 6 on the first and second pallet bodies 3, 19 limits the forward and backward movement of the machine body during transmission, ensuring stability and precise positioning of the machine body, improving processing accuracy and production efficiency. The proximity switch 7 is used to position the machine body on the pallet body, preventing it from exceeding the set movement distance.

[0031] One end of the pallet base plate 2 is connected to one end of the pallet back plate 1, and the other end of the pallet back plate 1 is connected to the lifting mechanism. The pallet body is connected to the lifting mechanism through the pallet base plate 2 and the pallet back plate 1. The hoist uses the hoist servo motor 9 to drive the ball screw 8 to adjust the height of the pallet. A laser displacement sensor 10 is fixed to the side of the hoist via the sensor support beam 11 to monitor the height of the pallet transmission system, thereby ensuring the accuracy of the conveying position of the pallet body.

[0032] The first active roller 13, the second active roller 15, and the driven roller 5 are embedded with ball bearings. Embedding ball bearings inside the rollers reduces friction between the rollers and the shaft through the free rolling of the balls, improving transmission efficiency and extending the service life of the equipment. Several driven rollers 5 are set at both ends of the first active roller 13, and several driven rollers 5 are set at both ends of the second active roller 15. The first active roller 13 and the second active roller 15 are connected by a rotating shaft 14. The first active roller 13 and the second active roller 15 are connected to the driving sprocket 16, and the driven roller 5 is connected to the driven sprocket 17. The first active roller 13, the second active roller 15, and the driven roller 5 are cylindrical transmission components driven by the pallet servo motor 4. In the elevator transmission pallet, the rollers are used to transport the machine body between different processes.

[0033] Here’s how to use it:

[0034] The machine body to be processed is first transferred from the conveyor belt of the upstream process to one side of the elevator drive pallet system and aligned with the limit guide rail 6. At this time, the pallet servo motor 4 drives the roller to start conveying the machine body. When the machine body reaches the specified position, the servo motor stops working to ensure that the machine body is accurately positioned on the pallet. Subsequently, the elevator starts to lift the pallet and the machine body to the specified height to meet the processing requirements of the next process. After reaching the specified height, the servo motor starts again and drives the roller to transfer the machine body from the pallet to the downstream process conveyor belt. After the machine body transfer is completed, the pallet returns to its initial position, ready to receive the next machine body, and the system repeats the above steps for the next round of conveying, positioning, height adjustment and processing operations.

[0035] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
