[0024] The present application will be further described below with reference to the accompanying drawings:

[0025] As Figs. 1 to 4The illustrated automatic material correction transfer line comprises a rack 1, a first conveying line 2 provided on the rack 1 and capable of conveying material 10, a stop block 3 provided on one side of the first conveying line 2 and capable of moving along the conveying direction of the first conveying line 2 and having a material correction operating state and a reset operating state, a driving assembly 4 provided on the rack 1 and capable of driving the stop block 3 to move, a first sensor 5 capable of detecting that the material 10 enters the first conveying line 2, and a second sensor 6 capable of detecting that the stop block 3 reaches the output end of the first conveying line 2. The transfer line further comprises a control system 7 capable of controlling the driving assembly 4 to drive the stop block 3 to enter the material correction operating state upon receiving a signal detected by the first sensor 5 that the material 10 enters the first conveying line 2, and capable of controlling the driving assembly 4 to drive the stop block 3 to enter the reset operating state upon receiving a signal detected by the second sensor 6 that the stop block 3 or the material 10 reaches the output end of the first conveying line 2. When the stop block 3 is in the material correction operating state, the linear speed of the stop block 3 is lower than the linear speed of the first conveying line 2, and the first conveying line 2 drives the material 10 to abut against the stop block 3 for correction. The material 10 can be a board or other product. The first sensor 5 and the second sensor 6 can be photoelectric sensors or other types of sensors.

[0026] In the present case, the linear speed of the stop block 3 is lower than the linear speed of the first conveying line 2 when the stop block 3 is in the material correction operating state, thereby forming a linear speed difference, and the first conveying line 2 is capable of driving the material 10 to abut against the stop block 3 for correction, reducing the possibility of material 10 deviation and improving the accuracy of material 10 conveying, without affecting the processing tempo of the entire production line. Compared with setting a guardrail on both sides of the conveying line to limit material deviation, the present application can better adapt to materials 10 of different sizes and shapes, increasing the versatility and flexibility of the transfer line. The automatic control system 7 reduces the need for manual intervention and reduces the operation complexity. Compared with a complex correction device such as a mechanical arm, the structure of the present application is relatively simple, easy to install, debug and maintain, and low in cost. At the same time, the entire transfer line is designed compactly and reasonably, fully utilizing the limited space on the rack 1 to realize efficient material correction function without affecting the layout of other production equipment.

[0027] In an embodiment, the control system 7 can be an electric control box, a PLC controller or a computer terminal.

[0028] In an embodiment, the belt driving assembly 4 comprises a second conveying line, which comprises a second conveyor belt 41 assembly. The second conveyor belt 41 assembly comprises a second conveyor belt 41, a second pulley set 42, and a first speed regulating motor 43 for driving the second pulley set 42 to rotate. The stop block 3 is fixedly connected to the conveying surface of the second conveying line, wherein the conveying surface is the outer surface of the second conveyor belt 41, and the stop block 3 can be connected to the second conveyor belt 41 by means of threaded fasteners or glue or other connecting structures. The first speed regulating motor 43 can be a servo motor, and of course can also be other speed regulating motors.

[0029] In an embodiment, the second conveying line comprises a second conveying chain assembly; the second conveying chain assembly comprises a second conveying chain, a second sprocket set, and a second speed regulating motor for driving the second sprocket set to rotate. The stop block 3 is fixedly connected to the conveying surface of the second conveying line, wherein the conveying surface is the outer surface of the second conveying chain, and the stop block 3 can be connected to the second conveying chain by means of threaded fasteners or glue or other connecting structures. The second speed regulating motor can be a servo motor, and of course can also be other speed regulating motors.

[0030] Further, the conveying surface of the second conveying line is lower than the conveying surface of the first conveying line 2, and the upper surface of the stop block 3 is higher than the conveying surface of the first conveying line 2, so that the conveying surface of the second conveying line does not affect the movement of the material 10.

[0031] In an embodiment, the first conveying line 2 comprises a first conveyor belt 21 assembly; the first conveyor belt 21 assembly comprises a first conveyor belt 21, a first pulley set 22, and a first motor 23 for driving the first pulley set 22 to rotate. The first motor 23 can be a servo motor, and of course can also be other types of motors.

[0032] In an embodiment, the first conveying line 2 comprises a first conveying chain assembly; the first conveying chain assembly comprises a first conveying chain, a first sprocket set, and a second motor for driving the first sprocket set to rotate. The second motor can be a servo motor, and of course can also be other types of motors.

[0033] In an embodiment, the running linear speed of the first conveying line 2 is S1, and the moving linear speed of the stopper 3 when it is in the material correction running state is S2, S1 / S2 = 3 / 2, the linear speed difference between the stopper 3 and the material 10 is small, reducing the impact force that may be generated when they meet. This not only protects the material 10 from damage, but also reduces the wear and tear of the stopper 3 and other mechanical parts caused by frequent collisions, prolonging the service life of the equipment. At the same time, it allows the material 10 to transition more smoothly from a free state to a constrained state, avoiding instability factors caused by sudden stops or rapid changes. This is very important for maintaining the stable operation of the entire system, especially when handling fragile or sensitive materials. By reasonably setting the speed of the stopper 3, the driving assembly 4 can work in a more energy-efficient manner without affecting the correction effect. This is because lower speed usually corresponds to less energy consumption, especially in the case of long-term operation, this design helps to reduce energy consumption costs. Among them, the running linear speed S1 is the same as the linear speed of the conveying line in the previous process.

[0034] In an embodiment, the moving linear speed of the stopper 3 when it is in the reset running state is S3, S3 / S1 ≥ 2, so that the stopper 3 can quickly return to the initial position and wait for the arrival of the next material 10.

[0035] In an embodiment, the first conveying line 2 includes a plurality of first conveying belts 21 arranged side by side and spaced apart on the rack 1, and the second conveying line includes a plurality of second conveying belts 41 arranged side by side and spaced apart on the rack 1, and the first conveying belts 21 and the second conveying belts 41 are arranged alternately.

[0036] By arranging the first conveying belts 21 and the second conveying belts 41 alternately, more conveying paths can be realized in a limited space, improving the space utilization of the entire system. Different numbers of conveying belts adapt to different sizes of materials 10. If a conveying belt fails, other conveying belts can still work to maintain the basic material 10 conveying function. Since the conveying belts are arranged alternately, it is not necessary to stop the entire production line when repairing or replacing a conveying belt. Technicians can focus on the conveying belts in a certain area without affecting other parts, thereby simplifying the maintenance process.

[0037] Further, the plurality of first conveyors 21 are driven by a first motor 23 to rotate a rotating shaft 20 to drive a plurality of first pulley sets 22, and the plurality of second conveyors 41 are driven by a first speed-regulating motor 43 to rotate a rotating shaft 20 to drive a plurality of second pulley sets 42. Compared with the case where each conveyor is independently provided with a driving device, this design reduces the number of motors and other driving components required, thereby simplifying the mechanical structure of the entire system. Since all the conveyors are driven by the same motor through the rotating shaft 20 and the pulley sets, the speed and phase of the conveyors can be kept highly consistent, ensuring smooth conveying of the materials 10 between different conveyors. The design of a single motor driving a plurality of conveyors facilitates more precise speed control, especially in the case of fine adjustment or synchronous operation.

[0038] In an embodiment, the first conveying line 2 includes a plurality of first conveying chains arranged side by side and spaced apart on the rack 1, and the second conveying line includes a plurality of second conveying chains arranged side by side and spaced apart on the rack 1, the first conveying chains being arranged alternately with the second conveying chains. The plurality of first conveying chains are driven by a second motor to rotate a rotating shaft 20 to drive a plurality of first sprocket sets, and the plurality of second conveying chains are driven by a second speed-regulating motor to rotate a rotating shaft 20 to drive a plurality of second sprocket sets. Compared with the case where each conveying chain is independently provided with a driving device, this design reduces the number of motors and other driving components required, thereby simplifying the mechanical structure of the entire system. Since all the conveying chains are driven by the same motor through the rotating shaft 20 and the sprocket sets, the speed and phase of the conveying chains can be kept highly consistent, ensuring smooth conveying of the materials 10 between different conveying chains. The design of a single motor driving a plurality of conveying chains facilitates more precise speed control, especially in the case of fine adjustment or synchronous operation.

[0039] Working principle:

[0040] The materials 10 are conveyed to the first conveying line 2 on the present transfer line through the previous process equipment. After the first sensor 5 detects that the materials 10 enter, a signal is sent to the control system 7, and the control system 7 issues an instruction to control the first motor 23 and the first speed-regulating motor 43 to start. The linear speed of the first conveying line 2 is consistent with that of the previous process equipment, while the linear speed of the stop block 3 is 2 / 3 of that of the first conveying line 2. Thus, a linear speed difference of 1 / 3 is formed. When the materials 10 move on the first conveying line 2, the first conveying line 2 with a faster speed provides a pushing force to the materials 10, pushing the materials 10 to the stop block 3, thereby achieving the function of aligning the materials 10, and without affecting the conveying rhythm of the equipment. When the stop block 3 runs to the tail end of the curved portion, the second sensor 6 senses the stop block 3 and sends a signal to the control system 7, which controls the first speed-regulating motor 43 to increase the speed to more than twice the linear speed of the first conveying line 2, rapidly accelerating the stop block 3 to rotate to the starting position, and waiting for the next material 10 to enter, thereby achieving a cycle of action.
