Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and specifically to an intelligent conveying and flipping system. Background Art

[0002] In the field of machining and manufacturing, workpieces usually need to go through multiple processes for processing. Many of these processes require front and back operations on the workpieces to ensure that the back side can also be effectively processed. To achieve this goal, traditional conveying systems usually need to integrate a flipping mechanism so that the workpieces can be automatically flipped during the conveying process to meet the requirements of subsequent processing.

[0003] However, there is a significant technical defect in the existing conveying and flipping systems: after the workpieces are flipped, they often cannot automatically disengage from the flipping mechanism and re-enter the conveying track, resulting in an interruption of the processing flow. Specifically, the design of the flipping mechanism mainly focuses on realizing the orientation conversion of the workpieces, but lacks an effective release mechanism, so that the flipped workpieces still stay in the flipping device and cannot smoothly flow into the next processing station. This problem forces the production system to introduce an additional transfer mechanism to pick up the workpieces from the flipping system and re-place them on the conveying mechanism by mechanical clamping or other means. The introduction of the transfer mechanism makes the structure of the entire conveying and flipping system more complex, not only increasing the equipment cost but also raising the maintenance difficulty; moreover, the additional transfer steps prolong the flow time of the workpieces and affect the overall production efficiency.

[0004] Therefore, there is an urgent need for a new type of conveying and flipping system to provide an effective solution to the defects of the existing technology.

[0005] Summary of the Invention

[0006] The purpose of the present invention is to provide an intelligent conveying and flipping system to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] An intelligent conveying and flipping system includes a feeding conveyor belt, a discharging conveyor belt, an interval conveyor belt, a flipping mechanism and a control module: The feeding conveyor belt, the discharging conveyor belt and the interval conveyor belt are located on the same straight line and have the same moving direction. The interval conveyor belt is located in front of the discharging conveyor belt. The flipping mechanism is located between the end of the feeding conveyor belt and the start end of the interval conveyor belt. The flipping mechanism includes a rotating shaft and a contact baffle. The axis of rotation of the rotating shaft is perpendicular to the moving directions of the feeding conveyor belt, the discharging conveyor belt and the interval conveyor belt. The contact baffle is used to sense workpieces. One or more clamping devices for clamping workpieces are provided on the rotating shaft. The clamping devices are perpendicular to the rotating shaft. The interval conveyor belt includes two or more independent sub-conveyor belts. An avoidance interval is provided between adjacent independent sub-conveyor belts for avoiding the clamping devices. The rotating shaft together with the workpieces and the clamping devices is driven to rotate by a motor. An angle sensor for sensing the rotation angle is provided at the end of the rotating shaft. The angle sensor, the motor and the clamping devices are electrically connected to the control module.

[0009] Further, the flipping mechanism has a pair of mounting bases separately arranged on both sides of the conveying path. A bearing seat is fixedly installed on each mounting base. The rotating shaft is rotatably installed on the pair of bearing seats. The motor and the angle sensor are respectively installed on one mounting base. A driving gear is fixedly installed on the output shaft of the motor. A driven gear is fixedly installed at the end of the rotating shaft. The driving gear and the driven gear are meshingly installed. The end of the telescopic rod of the telescopic motor is fixedly connected to the upper rail seat.

[0010] Further, a seat plate is fixedly connected to the rotating shaft. The clamping device includes an extension arm perpendicular to the rotating shaft. A pair of clamping jaws are slidably installed on the extension arm. The pair of clamping jaws are driven by a telescopic motor also installed on the extension arm to move synchronously towards or away from each other. An avoidance groove for avoiding the clamping jaws is provided on the contact baffle.

[0011] Further, a pair of outwardly protruding side rails are provided at the top and bottom of the extension arm respectively. A rail seat is provided at the top of the clamping jaw. The top side rail and the bottom side rail are each slidably installed with a rail seat.

[0012] Further, a rack extending towards the other rail seat is provided on each rail seat. The two racks are staggered up and down. A rack groove for avoiding the racks is provided in the middle of the extension arm. An intermediate gear is rotatably installed in the middle of the extension arm. The intermediate gear is meshingly installed with the upper and lower racks. The end of the telescopic rod of the telescopic motor is fixedly connected to the upper rail seat.

[0013] Further, the ends of the contact baffle are respectively connected to one mounting base. A fixed seat is provided on the inner side wall of each mounting base. A pressure sensor is provided between the end of the contact baffle and the fixed seat.

[0014] Furthermore, each of the inner side walls of the mounting base is fixedly mounted to a guide sleeve, a guide column is provided at both ends of the contact baffle, the guide column is slidably connected to the guide sleeve, a contact seat is provided at one end of the guide column away from the contact baffle, and the pressure sensor is installed between the contact seat and the fixed seat.

[0015] Furthermore, a spring hole is provided at one end of the guide column away from the contact baffle, a spring is connected in the spring hole, and the contact seat is connected to one end of the spring extending out of the spring hole.

[0016] Compared with the prior art, the novel beneficial effects of the present invention are:

[0017] 1. The present invention realizes the automatic circulation of workpieces through an intelligent avoidance and release mechanism. Through the precise coordination of the conveyor belt interval and the flipping mechanism, the workpiece can naturally detach from the clamping device after flipping, without the need for an additional transfer mechanism. The present invention simplifies the system structure, reduces the complexity of the equipment, and improves the production cycle. The entire process is controlled by a closed-loop sensor to ensure the precise synchronization of the action and the continuity of the production process.

[0018] 2. The present invention uses a gear rack linkage design through an optimized clamping drive mechanism to achieve precise synchronous movement of the clamping jaws. This symmetrical drive method ensures uniform force during the workpiece clamping process and effectively prevents the workpiece from shifting or falling off. With the precision guide structure, the clamping positioning accuracy is significantly improved, which is suitable for precision machining scenarios with high position accuracy requirements. At the same time, the overall structure is more compact, saving equipment installation space.

[0019] 3. The present invention improves reliability through the synergy of spring shock absorption and precision guidance through the buffer mechanism. The spring mechanism effectively absorbs the impact energy of the workpiece, which not only protects the sensor but also avoids damage to the workpiece. The linear guide design eliminates lateral interference and ensures the accuracy of the detection signal. The system can flexibly adapt to the detection needs of workpieces of different weights and shows excellent stability in a high-speed production environment. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] Next, the technical solutions in the new embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the new embodiments of the present invention. Obviously, the described embodiments are only a part of the new embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the new embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the new embodiments of the present invention.

[0033] Embodiment 1: Please refer to Figures 1 - 5, An intelligent conveying and flipping system, comprising a feeding conveyor belt 1, a discharging conveyor belt 4, an interval conveyor belt 32, a flipping mechanism 6 and a control module: The feeding conveyor belt 1, the discharging conveyor belt 4 and the interval conveyor belt 32 are located on the same straight line and have the same moving direction. The interval conveyor belt 32 is located on the front side of the discharging conveyor belt 4. The flipping mechanism 6 is located between the end of the feeding conveyor belt 1 and the starting end of the interval conveyor belt 32. The flipping mechanism 6 includes a rotating shaft 10 and a contact baffle 23. The axis of rotation of the rotating shaft 10 is perpendicular to the moving directions of the feeding conveyor belt 1, the discharging conveyor belt 4 and the interval conveyor belt 32. The contact baffle 23 is used to sense the workpiece 5. One or more clamping devices for clamping the workpiece 5 are provided on the rotating shaft 10. The clamping devices are perpendicular to the rotating shaft 10. The interval conveyor belt 32 includes two or more independent sub-conveyor belts 2. An avoidance interval 3 is provided between adjacent independent sub-conveyor belts 2. The avoidance interval 3 is used to avoid the clamping devices. The rotating shaft 10 together with the workpiece 5 and the clamping devices is driven to rotate by a motor 7. An angle sensor 22 for sensing the rotation angle is provided at the end of the rotating shaft 10. The angle sensor 22, the motor 7 and the clamping devices are electrically connected to the control module. The flipping mechanism 6 has a pair of mounting bases 25 separately arranged on both sides of the conveying path. A bearing seat 21 is fixedly mounted on each mounting base 25. The rotating shaft 10 is rotatably mounted on the pair of bearing seats 21. The motor 7 and the angle sensor 22 are respectively mounted on one mounting base 25. A driving gear 8 is fixedly mounted on the output shaft of the motor 7. A driven gear 9 is fixedly mounted at the end of the rotating shaft 10. The driving gear 8 and the driven gear 9 are meshingly mounted.

[0034] Working principle of this embodiment:

[0035] Automatic clamping and flipping mechanism (in combination with Figure 1 , Figure 2 , Figure 4 , Figure 5 ):

[0036] When the workpiece 5 is conveyed from the end of the feeding conveyor belt 1 to the flipping mechanism 6, the contact baffle 23 senses the workpiece in-place signal through the pressure sensor 24, triggering the clamping device to act. The clamping device clamps the workpiece 5. The rotating shaft 10 rotates 180° driven by the motor 7 (through the meshing of the gear pair 8, 9), driving the workpiece to complete the flipping. The angle sensor 22 monitors the rotation angle of the rotating shaft in real time to ensure accurate stopping. The control module adjusts the rotation speed and stopping position of the motor 7 in real time through the feedback of the angle sensor 22, and cooperates with the triggering signal of the contact baffle 23 to ensure that the clamping, flipping, and releasing actions are precisely synchronized. The flipping positioning accuracy is improved, the workpiece dropping or jamming is avoided, and the reliability of the production process is guaranteed. The above mechanism effectively solves the problem that the traditional flipping mechanism relies on manual intervention or additional transfer devices. Through the integrated clamping-flipping-releasing process, the process interruption is reduced and the continuous production efficiency is improved.

[0037] The avoidance interval design realizes automatic release (in combination with Figure 3, Figure 4 , Figure 5 ):

[0038] The spaced conveyor belt 32 consists of multiple independent sub-conveyor belts 2, and there is an avoidance interval 3 between adjacent sub-conveyor belts. During the flipping process, when the extension arm 13 and the clamping jaws 15 of the clamping device rotate to the lower part along with the rotating shaft 10, the avoidance interval 3 provides physical space for the clamping jaws, enabling the workpiece 5 to naturally disengage from the clamping and fall onto the spaced conveyor belt 32, and then being conveyed to the discharge conveyor belt 4. Without an additional transfer mechanism, by the collaborative design of the avoidance interval 3 and the clamping device, the automatic release of the workpiece is realized, the system structure is simplified, and the equipment cost and maintenance difficulty are reduced.

[0039] In this embodiment, through the integrated design of clamping - flipping - avoidance release and the closed-loop control of the sensor, the technical defects in the background art of the workpiece staying in the flipping mechanism and requiring additional transfer are effectively solved, and an efficient and low-cost automated production process is achieved.

[0040] Embodiment 2: Please refer to Figures 8 - 11 , an intelligent conveying and flipping system, which is different from Embodiment 1 in that a seat plate 11 is fixedly connected to the rotating shaft 10, the clamping device includes an extension arm 12, the extension arm 12 is perpendicular to the rotating shaft 10, a pair of clamping jaws 18 are slidably mounted on the extension arm 12, and the pair of clamping jaws 18 are driven by a telescopic motor 15 also mounted on the extension arm 12 to move synchronously towards or away from each other, and an avoidance groove 24 for avoiding the clamping jaws 18 is provided on the contact baffle 23.

[0041] A pair of outwardly protruding side rails 13 are provided at the top and bottom of the extension arm 12 respectively, a rail seat 17 is provided at the top of the clamping jaw 18, and one rail seat 17 is slidably mounted on each of the top side rail 13 and the bottom side rail 13.

[0042] A rack 19 extending towards the other rail seat 17 is provided on each rail seat 17, the two racks 19 are staggered up and down, a rack groove 14 for avoiding the racks 19 is provided in the middle of the extension arm 12, an intermediate gear 20 is rotatably mounted in the middle of the extension arm 12, the intermediate gear 20 is meshed with the upper and lower racks 19, and the end of the telescopic rod 16 of the telescopic motor 15 is fixedly connected to the upper rail seat 17.

[0043] The working principle of this embodiment:

[0044] Clamping drive mechanism: As shown in Figure 10 , the telescopic motor 15 pushes the upper rail seat 17 to move through the telescopic rod 16, driving the upper rack 19 to move. Through the transmission of the intermediate gear 20, the lower rack 19 is synchronously driven to move in the opposite direction, thereby realizing the synchronous movement of a pair of clamping jaws 18 towards or away from each other. As shown in Figure 7 , the avoidance groove 24 provided on the contact baffle 23 provides sufficient space for the movement of the clamping jaws 18 to avoid interference.

[0045] Guiding mechanism: As Figure 9 and Figure 11 shown, the side rails 13 provided at the top and bottom of the extension arm 12 and the rail seats 17 on the jaws 18 form a precision sliding pair, ensuring smooth movement of the jaws without deviation.

[0046] In this embodiment, the driving mechanism is fully integrated inside the extension arm 12. Through the optimized design of the rack groove 14 and the avoidance groove 24, the structure is compact and small. This embodiment realizes the collaborative optimization of clamping stability and space utilization, providing a reliable guarantee for high-precision machining.

[0047] Embodiment 3: Please refer to Figures 6 - 7 , an intelligent transmission and flipping system, which is different from Embodiment 1 in that the ends of the contact baffles 23 are respectively connected to a mounting base 25, and a fixing seat 30 is provided on the inner side wall of each mounting base 25. A pressure sensor 29 is provided between the end of the contact baffle 23 and the fixing seat 30.

[0048] A guide sleeve 31 is fixedly installed on the inner side wall of each mounting base 25. Guide posts 26 are provided at both ends of the contact baffle 23. The guide posts 26 are slidably connected to the guide sleeve 31. A contact seat 28 is provided at the end of the guide post 26 away from the contact baffle 23. The pressure sensor 29 is installed between the contact seat 28 and the fixing seat 30.

[0049] A spring hole is provided at the end of the guide post 26 away from the contact baffle 23, and a spring 27 is connected in the spring hole. The contact seat 28 is connected to the end of the spring 27 extending out of the spring hole.

[0050] Working principle of this embodiment:

[0051] As Figure 6 shown, when the workpiece 5 impacts the contact baffle 23, the guide post 26 slides in the guide sleeve 31 to compress the spring 27, and the impact force is reduced through the buffering action of the spring 27. The contact seat 28 transmits the remaining pressure to the pressure sensor 29 for precise detection. The precise fit between the guide post 26 and the guide sleeve 31 (as Figure 7 shown) ensures that the contact baffle 23 always moves in a straight line, avoiding detection errors caused by skewing. The pre-tightening force of the spring 27 can be adjusted according to the weight of different workpieces, ensuring reliable detection of light workpieces and preventing damage to the sensor and the workpiece itself due to the impact of heavy workpieces.

[0052] Through the buffer mechanism, this embodiment realizes a comprehensive improvement in detection accuracy, anti-impact performance and adaptability on the basis of maintaining the original detection function. It is especially suitable for the detection scenario of heavy workpieces on high-speed production lines, solving the defects of traditional rigid detection mechanisms that are easy to damage and easy to damage workpieces.
