Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to an automatic positioning device for a robotic loading trolley. Background Technology

[0002] Material handling trolleys are one of the main pieces of equipment in industrial processing and manufacturing, widely used in automated production lines in industries such as metallurgical processing and non-ferrous metals. Items are often transferred between different processes using rail-guided trolleys, which are typically driven by electric motors. The motor rotates forward, and the trolley moves backward. With the rapid development of industrial robot technology, loading robots are increasingly widely used in material handling equipment, especially in situations involving complex blanks or harsh working conditions, particularly in flexible manufacturing systems. Loading robots are responsible for loading materials onto material handling trolleys, forming automated loading devices that effectively reduce the workload of workers and significantly improve work efficiency.

[0003] In some existing material handling trolleys, when working with a loading robot, the material handling trolley shuts off its walking motor when it reaches the loading position. However, due to inertia, the material handling trolley may not be able to reach the designated position precisely, or the material handling trolley may shift due to unevenness of the track. This causes the loading robot and the material handling trolley to be unable to position themselves accurately, affecting the normal operation of the loading equipment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing material handling trolleys when working with a loading robot. When the material handling trolley reaches the loading position, it shuts off its walking motor, but the trolley may not accurately reach the designated position due to inertia, or the material handling trolley may shift due to uneven track, resulting in the loading robot and the material handling trolley not being accurately positioned, thus affecting the normal operation of the loading equipment. This invention provides an automatic positioning device for a robot loading trolley.

[0005] The purpose of this utility model is achieved through the following technical solution: an automatic positioning device for a robot loading trolley, including a material transport trolley and a loading robot. The material transport trolley is installed on a track, and the loading robot is installed on a base. The base is located on one side of the track. The track is provided with a loading station corresponding to the loading robot. The material transport trolley is equipped with a walking motor for driving the material transport trolley to move on the track.

[0006] An infrared receiver is installed at the front end of the material transport trolley, and a first infrared transmitter adapted to the infrared receiver is installed on the base. The first infrared transmitter is installed on the side of the base near the entrance of the loading station. The infrared receiver is electrically connected to the walking motor.

[0007] The base is equipped with a first servo motor and a second servo motor, which are respectively located on both sides of the feeding robot. The power output ends of the first servo motor and the second servo motor are equipped with limit plates corresponding to the material transport trolley. The first servo motor and the second servo motor are electrically connected to the infrared receiver.

[0008] By configuring an infrared receiver to be compatible with a first infrared transmitter on the base near the entrance of the loading station, and by electrically connecting the infrared receiver to the motor that drives the material handling trolley to move on the track, the infrared receiver can receive a signal from the first infrared transmitter when the material handling trolley enters the loading station, controlling the motor to stop working. This allows the material handling trolley to decelerate and move into the loading station by inertia. The infrared receiver is also electrically connected to a first servo motor and a second servo motor, which control the first and second servo motors to rotate the limit plates toward the material handling trolley, thereby limiting and fixing the trolley and ensuring its precise positioning at the loading station. This guarantees the normal operation of the material handling trolley and the loading robot. At the same time, the two sets of limit plates are located on both sides of the material handling trolley, which can effectively adjust the position of the trolley and ensure the accuracy of its final position.

[0009] A further technical solution is to install a second infrared transmitter on the base, which is compatible with the infrared receiver. The second infrared transmitter is installed on the side of the base near the outlet of the loading station. By setting the second infrared transmitter to work in conjunction with the infrared receiver, it is possible to monitor whether the final position of the material conveying trolley is accurate and avoid deviations that could cause equipment loading failures.

[0010] A further technical solution is to electrically connect the infrared receiver to the loading robot. By setting the infrared receiver to be electrically connected to the loading robot, it can be determined that the positioning of the material handling trolley is accurate when the infrared receiver stably receives the signal from the second infrared transmitter for a long time. Then, the infrared receiver sends a signal to the loading robot to control the loading robot to load materials, thus ensuring the stability of equipment operation.

[0011] A further technical solution is to use two sets of limit plates to fix and limit the material transport trolley. Each set of limit plates has a rubber pad installed on the side closest to the material transport trolley. By setting the rubber pad on the limit plate, the impact force between the limit plate and the material transport trolley can be reduced when the limit plate collides with the material transport trolley, thereby reducing wear and ensuring the service life of the equipment.

[0012] A further technical solution is to install universal self-locking wheels on the bottom surface of the base and a handle on the base. By setting the handle to cooperate with the universal self-locking wheels, it is easy to adjust the position of the loading robot and the base, thereby facilitating the adjustment of the position of the loading station and improving the ease of use.

[0013] This utility model has the following advantages: By setting an infrared receiver that is compatible with a first infrared transmitter on the base near the entrance of the loading station, and electrically connecting the infrared receiver to the walking motor that drives the material transport trolley to move on the track, the infrared receiver can receive a signal from the first infrared transmitter when the material transport trolley enters the loading station to control the walking motor to stop working, so that the material transport trolley decelerates and moves into the loading station by inertia. The infrared receiver is electrically connected to the first servo motor and the second servo motor, and controls the first servo motor and the second servo motor to drive the limit plate to rotate towards the material transport trolley, thereby limiting and fixing the material transport trolley, so that the material transport trolley is accurately positioned on the loading station, ensuring the normal operation of the material transport trolley and the loading robot. At the same time, the two sets of limit plates are located on both sides of the material transport trolley, which can effectively adjust the position of the material transport trolley and ensure the accuracy of the final position of the material transport trolley.

[0024] like Figures 1-3 As shown, an automatic positioning device for a robot loading trolley includes a material handling trolley 1 and a loading robot 2. The material handling trolley 1 is mounted on a track 3, and the loading robot 2 is mounted on a base 4. The base 4 is located on one side of the track 3. The track 3 is provided with a loading station corresponding to the loading robot 2. The material handling trolley 1 is equipped with a walking motor 7 for driving the material handling trolley 1 to move on the track 3.

[0025] An infrared receiver 6 is installed at the front end of the material transport trolley 1, and a first infrared transmitter 5 adapted to the infrared receiver 6 is installed on the base 4. The first infrared transmitter 5 is installed on the side of the base 4 near the entrance of the loading station. The infrared receiver 6 is electrically connected to the walking motor 7.

[0026] The base 4 is equipped with a first servo motor 8 and a second servo motor 9. The first servo motor 8 and the second servo motor 9 are respectively located on both sides of the loading robot 2. The power output ends of the first servo motor 8 and the second servo motor 9 are equipped with limit plates 10 corresponding to the material handling trolley 1. The first servo motor 8 and the second servo motor 9 are electrically connected to the infrared receiver 6.

[0027] By configuring an infrared receiver 6 to be compatible with a first infrared transmitter 5 on the base 4 near the entrance of the loading station, and by electrically connecting the infrared receiver 6 to the walking motor 7 that drives the material handling trolley 1 to move on the track 3, the infrared receiver 6 can receive a signal from the first infrared transmitter 5 when the material handling trolley 1 enters the loading station, controlling the walking motor 7 to stop working, so that the material handling trolley 1 decelerates and moves into the loading station by inertia. The infrared receiver 6 is electrically connected to the first servo motor 8 and the second servo motor 9, and controls the first servo motor 8 and the second servo motor 9 to drive the limiting plate 10 to rotate toward the material handling trolley 1, thereby limiting and fixing the material handling trolley 1, so that the material handling trolley 1 is accurately positioned on the loading station, ensuring the normal operation of the material handling trolley 1 and the loading robot 2. At the same time, the two sets of limiting plates 10 are located on both sides of the material handling trolley 1, which can effectively adjust the position of the material handling trolley 1 and ensure the accuracy of the final position of the material handling trolley 1.

[0028] A second infrared transmitter 14 adapted to the infrared receiver 6 is installed on the base 4. The second infrared transmitter 14 is installed on the side of the base 4 near the outlet of the loading station. By setting the second infrared transmitter 14 to cooperate with the infrared receiver 6, it is possible to monitor whether the final position of the material transport trolley 1 is accurate and avoid deviations that may cause equipment loading failure.

[0029] The infrared receiver 6 is electrically connected to the loading robot 2. By setting the infrared receiver 6 to be electrically connected to the loading robot 2, it is possible to determine that the positioning of the material handling trolley 1 is accurate when the infrared receiver 6 stably receives the signal from the second infrared transmitter 14 for a long time. Thus, the infrared receiver 6 sends a signal to the loading robot 2 to control the loading robot 2 to load materials, ensuring the stability of the equipment operation.

[0030] Two sets of limit plates 10 are responsible for fixing and limiting the material transport trolley 1. Each set of limit plates 10 has a rubber pad 11 installed on the side of the material transport trolley 1. By setting the rubber pad 11 on the limit plate 10, the impact force between the limit plate 10 and the material transport trolley 1 can be reduced when the limit plate 10 collides with the material transport trolley 1, thereby reducing wear and ensuring the service life of the equipment.

[0031] The bottom surface of the base 4 is equipped with a universal self-locking wheel 13, and a handle 12 is installed on the base 4. By setting the handle 12 to cooperate with the universal self-locking wheel 13, it is easy to adjust the position of the loading robot 2 and the base 4, thereby facilitating the adjustment of the position of the loading station and improving the ease of use.

[0032] The working process of this utility model is as follows: First, when the material transport trolley 1 enters the loading station entrance, the infrared receiver 6 at the front end of the material transport trolley 1 receives the signal from the first infrared transmitter 5. At this time, the infrared receiver 6 controls the walking motor 7 to stop working, and the material transport trolley 1 continues to slide on the track 3 by inertia. At the same time, the infrared receiver 6 sends signals to the first servo motor 8 and the second servo motor 9. The first servo motor 8 and the second servo motor 9 respectively drive the two sets of limit plates 10 to rotate toward the material transport trolley 1. The first servo motor 8 and the second servo motor 9 control the two sets of limit plates 10 to push the material transport trolley 1 to the loading station. At this time, after the infrared receiver 6 can stably receive the signal from the second infrared transmitter 14 for a long time, the infrared receiver 6 sends a signal to the loading robot 2. The loading robot 2 begins to load the material transport trolley 1. After the loading is completed, the first servo motor 8 and the second servo motor 9 drive the limit plates 10 to reset, and the walking motor 7 drives the material transport trolley 1 to continue moving and drive out of the loading station.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
