Description

TECHNICAL FIELD

[0001] The utility model relates to automatic technology field especially relates to a take material module based on sensor. BACKGROUND

[0002] In modern automation production and logistics system, material taking and placing and the interval between materials directly affect the operation effect of the whole production line. The traditional material taking module usually relies on fixed interval grabbing device or manual adjustment of material position, which has some defects. For example, the traditional device is difficult to dynamically adjust the material interval, which leads to uneven distribution of materials on the conveyor belt, affecting subsequent processing or assembly and other processes. Most systems lack real-time sensing feedback and need to rely on preset programs or manual intervention, and cannot automatically adjust the mechanical arm or interval adjustment mechanism according to the material state such as position, which lacks flexibility. The grabbing action of the mechanical arm lacks intelligent cooperation with the conveyor belt, which is prone to empty grabbing, missed grabbing or collision problems, increasing the risk of downtime maintenance. In the prior art, although some schemes detect the position of the material through a single sensor, they fail to integrate the linkage control of dynamic interval adjustment and grabbing action, resulting in slow system response speed or complex structure. In addition, the cooperation logic of the sensor and the actuator is not perfect, and it is difficult to balance efficiency and stability. Therefore, it is necessary to provide a material taking module based on sensor. SUMMARY

[0003] The utility model aims at solving at least one of the above technical problems.

[0004] To solve the above problems, the first purpose of the utility model is to provide a material taking module based on sensor, which comprises: a grabbing device; a material interval adjustment device provided with a first sensor and an interval adjustment rod; and a conveyor belt, the grabbing device and the material interval adjustment device being connected to the conveyor belt.

[0005] If the material interval is too small, some visual detection systems such as camera and laser scanner may misjudge such as miss defects and misread bar codes due to overlapping or edge adhesion of materials, and the material interval adjustment device can separate materials with too close distance to avoid shielding interference. In addition, the interval distance between materials is sufficient to avoid the phenomenon of material jam in subsequent packaging and sorting processes. Fragile or precision materials such as glass bottles and electronic components may collide with each other in conveying due to too small interval, and adjusting the interval can reduce the breakage rate. In high-speed assembly line, the interval adjustment device can be used as a dynamic buffer zone to balance the speed difference between grabbing and subsequent processes, avoiding congestion or material breakage.

[0006] In the above technical solution, the interval adjustment rod has a retracted state and an extended state, and the length of the interval adjustment rod in the retracted state is less than the length of the interval adjustment rod in the extended state.

[0007] In the retracted state, the length of the adjustment rod is shortened, the occupied space is reduced, and the normal transportation of materials is avoided. In the non-working stage, the adjustment rod is retracted to avoid interference with other mechanisms such as mechanical arms, conveyors, etc. Only when the material spacing is too small, the adjustment rod is extended, and the normal spacing material is adjusted to reduce invalid operation. The telescopic structure such as cylinder or linear motor drive is more agile than the fixed type separation device, and is suitable for high-speed assembly line. Only when it is necessary to contact the material, the continuous friction between the adjustment rod and the material is reduced, and the service life is prolonged. In the extended state, the length of the adjustment rod is extended, the subsequent material is blocked, and the distance between the materials can be separated. Through sensor feedback, the state is adjusted in real time, and multiple specifications of materials can be produced without manual hardware replacement.

[0008] In any of the above technical solutions, the first sensor has an activated state and a non-activated state. In the activated state, the spacing adjustment rod becomes an extended state, and in the non-activated state, the spacing adjustment rod becomes a retracted state.

[0009] Only when the first sensor detects that the material passes through, the first sensor becomes activated and the spacing adjustment rod is extended to intercept the subsequent material, ensuring the real-time and targeted adjustment of the spacing and avoiding invalid actions. When there is no material passing through the first sensor, the spacing adjustment rod is retracted to reduce mechanical wear and energy consumption. The spacing adjustment rod is only extended when needed, and will not continuously hinder the conveyor belt, ensuring that the unadjusted material passes normally and reducing the impact on the overall flow rate. It is suitable for high-speed assembly line, and the sensor feedback in real time plus the quick extension and retraction of the adjustment rod make it more efficient than the fixed type separation mechanism. Only when the material is detected, the mechanism is activated to avoid mechanical interference caused by empty running or false triggering. Automatic operation without manual intervention reduces downtime and adjustment time. The adjustment rod only works when necessary, reducing wear caused by long-term friction and prolonging the service life. When the spacing of the materials is uneven, dynamic separation is used to ensure detection accuracy.

[0010] In any of the above technical solutions, the gripping device is provided with a second sensor connected to the conveyor belt.

[0011] The second sensor detects the empty space, obstacles or abnormal state such as accumulation or deviation on the conveyor belt, ensuring that the gripping device releases the material only when it is safe to do so, avoiding production interruptions caused by falling, collision or accumulation. When the sensor detects that the target position of the conveyor belt is occupied, such as when the previous material has not been removed, the conveyor belt can be paused or the placement action of the gripping device can be delayed to avoid material jamming or damage caused by forced placement. Synchronous beat, closed-loop control with upstream and downstream, solves the problem of beat mismatch between processes. On a narrow conveyor belt, the sensor ensures that a minimum safety distance is maintained between adjacent materials to prevent collision and achieve high-density conveying optimization. Avoiding the empty operation or mechanical wear caused by blind placement of the gripping device.

[0012] In any of the technical solutions above, the grabbing device is provided with a mechanical arm, and the mechanical arm is connected with the second sensor.

[0013] The second sensor dynamically monitors the state of the conveying belt during movement of the mechanical arm, such as whether there is an obstacle, whether the previous material has been removed, to ensure that the mechanical arm releases the material only in a safe position, preventing the mechanical arm from dropping the material or colliding with the conveying belt. If the sensor detects an abnormality in the target position, such as deviation or material stacking, the mechanical arm can automatically adjust the placement point or pause the action, waiting for manual intervention, reducing the risk of hard failure. When the sensor detects that the conveying belt is not ready, such as full material or blocked material, the mechanical arm can pause the grabbing action to avoid the invalid cycle of grabbing but not placing. On a narrow or high-speed conveying belt, the sensor guides the mechanical arm to accurately insert into the material gap, avoiding the extrusion of adjacent materials. Through the preventive intervention of the sensor, the mechanical arm is prevented from causing motor overload or clamp wear due to blind placement.

[0014] In any of the technical solutions above, the mechanical arm has a hovering state and a placement state, in the hovering state the mechanical arm is close to the conveying belt, and in the placement state the mechanical arm is away from the conveying belt.

[0015] The mechanical arm hovers at a close distance before releasing the material, and the target position is verified in real time by the second sensor to ensure that the placement conditions are met, preventing the material from falling, colliding or misplacing due to blind placement. After releasing the material, the mechanical arm is quickly lifted to avoid interfering with the flow of the conveying belt or other materials, reducing the risk of scratching or interference. If the second sensor detects an abnormality in the conveying belt, such as blocked material, the mechanical arm remains in the hovering state until the conveying belt is restored, reducing the delay of restarting. In a compact layout production line, the hovering state reduces the longitudinal movement space occupied by the mechanical arm, avoiding interference with surrounding equipment.

[0016] In any of the technical solutions above, the second sensor has an empty state and a loaded state, in the empty state the mechanical arm becomes the placement state, and in the loaded state the mechanical arm becomes the hovering state.

[0017] When the second sensor is in the empty state, it means that the second sensor detects that there is no material in the target position of the conveying belt, and the mechanical arm immediately performs the placement action to ensure that the material is accurately placed in the effective empty position, avoiding stacking, collision or material tilting due to position occupation. When the second sensor is in the loaded state, it means that the second sensor detects that there is material in the target position, and the mechanical arm automatically remains in the hovering state to prevent material extrusion, equipment collision or mechanical overload caused by forced placement. The mechanical arm only performs the placement action when the sensor confirms the empty state, avoiding the time-consuming operation of trial placement and significantly improving the efficiency of the assembly line.
