Description

Technical Field

[0001] This utility model relates to the field of automated conveying equipment technology, specifically a device for precise control and positioning of a belt conveyor mechanism. Background Technology

[0002] In automated production lines, precise positioning of the pallet is crucial for ensuring accurate material handling. Traditionally, pallets are driven by belt friction, but this method suffers from slippage and speed fluctuations, resulting in low pallet positioning accuracy and failing to meet the demands of high-precision production.

[0003] To address these issues, existing technologies employ a drive system where a synchronous belt meshes with the carrier disc teeth. This meshing of the synchronous belt teeth and the carrier disc mounting teeth improves positioning accuracy. However, in double-layer streamlined designs, the carrier disc typically uses an insertion structure when flowing back from the upper layer to the lower layer, requiring the disc to be accurately inserted into the positioning slot of the lower conveyor track. Since the synchronous belt teeth and carrier disc teeth may slightly misalign during long-term operation, forcibly inserting the disc before complete alignment can cause a violent impact between the disc and the track, damaging the equipment and potentially disrupting production cycles.

[0004] In the existing technology, the solutions to this problem mostly rely on mechanical guiding structures or adding manual calibration steps. However, mechanical guidance is easily affected by vibration, which leads to a decrease in accuracy, while manual calibration is inefficient and cannot achieve full automation. Utility Model Content

[0005] The purpose of this utility model is to provide a device for precise control and positioning of a belt conveyor mechanism. By installing the lower conveyor mechanism and the upper conveyor mechanism, the device for precise control and positioning of the belt conveyor mechanism has high-precision alignment, dynamic adaptability and safety stability, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for precise control and positioning of a belt conveyor mechanism, comprising:

[0008] An upper conveying mechanism, with a lower conveying mechanism fixedly installed at its lower end;

[0009] The lower conveying mechanism includes an encoder for real-time acquisition of the rotation angle signal of the drive shaft. The lower end of the encoder is connected to a coupling provided at one end of the conveying mechanism, and the lower end of the coupling is connected to the drive shaft provided at the same end of the conveying mechanism.

[0010] The conveying mechanism has meshing teeth spaced apart on the outer side of the synchronous belt, and a guide rail seat is provided on one side of the conveying mechanism.

[0011] As a further technical solution of this utility model, the meshing teeth are meshed with the positioning teeth, the positioning teeth are located on one side of the carrier plate, and the lower end of the carrier plate is provided with a sliding groove, which is slidably connected to the guide rail seat.

[0012] As a further technical solution of this utility model, the conveying mechanism and the guide rail are mounted on multiple connecting plates, and connecting frames are symmetrically fixedly installed at both ends of the connecting plates, wherein the upper end of the front connecting frame is fixedly connected to the mounting frame.

[0013] As a further technical solution of this utility model, linear module one and linear module two are fixedly installed on the left and right ends of the mounting frame, respectively; a magnetic levitation transport seat one is connected to linear module one, and a guide rail is provided on the magnetic levitation transport seat one.

One side of the multiple magnetic levitation rails is fixedly installed on the connecting frame at the rear end of multiple connecting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In use, the encoder provides real-time feedback on the position of the drive shaft, controlling the positioning error within the minimum range allowed by the mechanical structure. This solves the problem of traditional mechanical guides being easily affected by vibration. No manual calibration is required. The system can automatically adjust the conveying speed of the conveying mechanism based on real-time detection data, adapting to the slight changes in the meshing teeth of the synchronous belt during long-term operation.

[0017] 2. In this utility model, when the encoder signal shows that the synchronous belt meshing teeth are fully aligned with the positioning teeth on the carrier plate, the control module issues an insertion permission command. The carrier plate accurately docks with the guide rail at the upper end of the guide rail seat during uniform motion, avoiding rigid impact with the guide rail seat, extending the equipment life and improving the stability of continuous operation of the production line.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 In this embodiment of the utility model, a device for precise control and positioning of a belt conveyor mechanism includes an upper conveyor mechanism 1, and a lower conveyor mechanism 2 is fixedly installed at the lower end of the upper conveyor mechanism 1.

[0031] The lower conveying mechanism 2 includes an encoder 23 for real-time acquisition of the rotation angle signal of the drive shaft. The lower end of the encoder 23 is connected to a coupling provided at one end of the conveying mechanism 22, and the lower end of the coupling is connected to the drive shaft provided at the same end of the conveying mechanism 22.

[0032] The conveying mechanism 22 has meshing teeth 24 spaced apart on the outer side of the synchronous belt, and a guide rail seat 21 is provided on one side of the conveying mechanism 22.

[0033] By adopting the above technical solution, the encoder 23 provides real-time feedback on the position of the drive shaft during use, controlling the positioning error within the minimum range allowed by the mechanical structure. This solves the problem that traditional mechanical guides are easily affected by vibration. No manual calibration is required. The system can automatically adjust the conveying speed of the conveying mechanism 22 based on real-time detection data, adapting to the slight changes in the meshing teeth 24 of the synchronous belt during long-term operation.

[0034] In this embodiment, the meshing tooth 24 is meshed with the positioning tooth 110. The positioning tooth 110 is located on one side of the carrier plate 17. The lower end of the carrier plate 17 is provided with a sliding groove, which is slidably connected to the guide rail seat 21.

[0035] The conveying mechanism 22 and guide rail seat 21 are mounted on multiple connecting plates 15. Connecting frames 14 are symmetrically fixedly mounted at both ends of the connecting plates 15, wherein the upper end of the front connecting frame 14 is fixedly connected to the mounting frame 11.

[0036] The mounting frame 11 has a linear module 12 and a linear module 2 18 fixedly mounted on its left and right ends, respectively; the linear module 12 is connected to a magnetic levitation transport seat 13, and the magnetic levitation transport seat 13 is provided with a guide rail.

[0037] The linear module 2 18 is connected to a magnetic levitation transport seat 2 19. The magnetic levitation transport seat 2 19 is provided with a guide rail, and multiple magnetic levitation rails 16 are provided between the magnetic levitation transport seat 1 13 and the magnetic levitation transport seat 2 19. The multiple magnetic levitation rails 16 are fixedly installed on one side of the connecting frame 14 at the rear end of the multiple connecting plates 15.

[0038] By adopting the above technical solution, when the encoder 23 signal shows that the synchronous belt meshing tooth 24 is fully aligned with the positioning tooth 110 on the carrier plate 17, the control module issues an insertion permission command. The carrier plate 17 accurately docks with the guide rail at the upper end of the guide rail seat 21 during uniform motion, avoiding rigid impact with the guide rail seat 21, extending the equipment life and improving the stability of continuous operation of the production line.

[0039] The working principle of this utility model is as follows: the trays 17 arranged in an array first slide on multiple magnetic levitation rails 16 through the grooves at the lower end, slide to the guide rail of the magnetic levitation transport seat 13, and then the trays 17 are transported to the guide rail seat 21 at the lower end through the linear module 12; at this time, the control module starts the encoder 23 high-precision sampling mode to calculate the current position of the synchronous belt meshing teeth 24 on the conveying mechanism 22 in real time.

[0040] There is a preset deviation range between the theoretical alignment of the positioning teeth 110 on the carrier plate 17 and the synchronous belt meshing teeth 24 on the conveying mechanism 22. If the encoder 23 detects that the actual position deviation exceeds the threshold, the control module sends a deceleration signal to the drive motor on the conveying mechanism 22 until the deviation is reduced to a safe range. When the encoder 23 signal shows that the synchronous belt meshing teeth 24 and the positioning teeth 110 on the carrier plate 17 are fully aligned, the control module issues an insertion permission command. The carrier plate 17 accurately docks with the guide rail at the upper end of the guide rail seat 21 during uniform motion, avoiding rigid impact with the guide rail seat 21, extending the equipment life and improving the stability of continuous operation of the production line.

[0041] When the carrier plate 17 moves to one end of the encoder 23 installed on the conveying mechanism 22, the carrier plate 17 is connected to the guide rail on the magnetic levitation transport seat 19, and then the linear module 18 drives the carrier plate 17 to rise to one end of the magnetic levitation seat rail 16.

[0042] During use, the encoder 23 provides real-time feedback on the position of the drive shaft, keeping the positioning error within the minimum range allowed by the mechanical structure. This solves the problem of traditional mechanical guides being susceptible to vibration interference. No manual calibration is required. The system can automatically adjust the conveying speed of the conveying mechanism 22 based on real-time detection data, adapting to the slight changes in the meshing teeth 24 of the synchronous belt during long-term operation.
