Description

Technical Field

[0001] This utility model relates to the field of robotics, and in particular to a buffer handling device. Background Technology

[0002] Flower baskets play a crucial role in the manufacturing processes of the semiconductor and photovoltaic industries. They are essential carriers for silicon wafers (semiconductor industry) and solar cells (photovoltaic industry), providing a stable storage and transport environment for these delicate wafers during production. Silicon wafers and solar cells have extremely high requirements for surface quality; even minor scratches or collisions can lead to product failure. Flower baskets effectively ensure their physical integrity throughout the production process.

[0003] In the production process, the buffer handling device plays a crucial role in transporting flower baskets. To prevent the flower baskets from accidentally tipping over and falling off the robot during handling, existing technologies typically employ movable stop mechanisms. These mechanisms are usually located below the conveyor mechanism. However, considering the installation space below the conveyor mechanism, the lifting stroke of the movable stop mechanism is usually small, thus only able to block the flower basket near its bottom. While this movable stop mechanism reduces the possibility of the flower basket falling to some extent, problems still exist in practical applications.

[0004] With the expansion of production scale and the improvement of production efficiency, the moving speed, start-stop frequency, and complexity of the working environment of buffer handling devices are all increasing. During the frequent movement of the buffer handling device, due to various factors, such as the inertial forces generated when the robot accelerates, decelerates, and turns, or the bumps and vibrations caused by running on uneven ground, the movable stop mechanism may fail to stop the basket due to its high center of gravity, causing the basket to tip over. Once the basket falls, it will damage the silicon wafers or solar cells, which not only brings high economic losses, but may also affect the production schedule and product quality, reducing the reliability and stability of the entire production process. Therefore, there is an urgent need for a more effective solution to completely solve the problem of baskets falling during buffer handling. Utility Model Content

[0020] Furthermore, the buffer handling device also includes a housing, which is connected to the frame above and to the side of the buffer space. The housing has a material transfer port facing the positive X-axis direction. The conveying mechanism is located at the bottom of the housing and passes through the material transfer port.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0033] See Figures 1 to 5 As shown, this is one embodiment of the cache transport device provided by the present invention.

[0034] The buffer handling device is used to move flower baskets. The buffer handling device includes:

[0035] Mobile mechanism 1, which can be moved to different locations;

[0036] Conveying mechanism 2 is mounted on the moving mechanism 1. Above the conveying mechanism 2 is a buffer space 3. The conveying mechanism 2 is used to carry materials and drive the materials to move along the X-axis.

[0037] A movable stop mechanism is provided to restrict the translation and dumping of materials in the buffer space 3 in the positive X-axis direction. The movable stop mechanism includes a drive device 41 and a stop member 42. The drive device 41 drives the stop member 42 to move between a stop position and a release position. When the stop member 42 is in the stop position, it is located on the positive X-axis side of the buffer space 3 and is in contact with at least the center of gravity of the materials in the buffer space 3 or a position above the center of gravity. When the stop member 42 is in the release position, it moves away from the positive X-axis side of the buffer space 3.

[0038] The aforementioned moving mechanism 1 can move to different locations, thereby transporting the flower basket from one place to another. The aforementioned conveying mechanism 2 carries the material and drives the material to translate along the X-axis, thereby moving the flower basket from outside the buffer space 3 to inside the buffer space 3 and from inside the buffer space 3 to outside the buffer space 3. Generally, the conveying mechanism 2 exchanges flower baskets with other conveying mechanisms outside the buffer space 3. The aforementioned movable stop mechanism is configured to be movable, used to block the movement of the flower basket or to release the flower basket.

[0039] When the stop member 42 of the aforementioned movable stop mechanism is in the stop position, by setting the position of the stop member 42, the stop member 42 is in contact with at least or above the center of gravity of the flower basket. Under various working conditions, it can prevent the flower basket from falling or tipping over when the robot is carrying the flower basket, avoid economic losses, prevent the impact on production progress and product quality, and ensure the reliability and stability of the entire production process.

[0040] In this embodiment, the driving device 41 is horizontally disposed above the buffer space 3, the stop 42 is a stop bar extending in the vertical direction, the driving device 41 is connected to the upper end of the stop 42 and drives the stop 42 to translate along the Y-axis direction.

[0041] The drive device 41 is horizontally positioned above the buffer space 3, and the stop 42 extends vertically. The drive device 41 drives the stop 42 to translate along the Y-axis. While reliably preventing the flower basket from falling or tipping over, the dimensions of the entire buffer transport device in all directions do not increase significantly.

[0042] In this embodiment, when the stop member 42 is in the stop position, the lower end of the stop member 42 contacts the center of gravity or a position below the center of gravity of the material in the buffer space 3.

[0043] The lower end of the stop 42 contacts the center of gravity of the flower basket in the buffer space 3 or a position below the center of gravity, which increases the contact area between the stop 42 and the flower basket and further improves the reliability of the stop 42 in preventing the flower basket from falling or tipping over.

[0044] In this embodiment, the driving device 41 is a telescopic driving device, and one end of the telescopic driving device 41 along the telescopic direction is rotatably connected to the frame 5 above the buffer space 3 in the vertical direction.

[0045] The aforementioned movable stop mechanism also includes:

[0046] Translation guide 43 extends along the Y-axis and is mounted on the frame 5 above the buffer space 3;

[0047] Translation component 44, which is movably connected to translation guide component 43 along the Y-axis direction;

[0048] Connecting seat 45, the connecting seat 45 is connected to the translation member 44, and the connecting seat 45 is connected to the stop member 42;

[0049] First connecting rod 46, one end of which is rotatably connected to the connecting seat 45 about the vertical direction;

[0050] The second link 47 has one end rotatably connected to the other end of the first link 46 in a vertical direction, and the other end of the second link 47 rotatably connected to the frame 5 above the buffer space 3 in a vertical direction. The middle section of the second link 47 is rotatably connected to the other end of the telescopic drive device 41 in the telescopic direction.

[0051] The aforementioned frame 5 is mounted on the moving mechanism 1. The telescopic drive device 41 is connected to the frame 5 above the buffer space 3 via the first hinge seat 48, and the second connecting rod 47 is connected to the frame 5 above the buffer space 3 via the second hinge seat 49. The aforementioned translation guide 43 is a guide rail, and the aforementioned translation member 44 is a slider. When the drive device 41 extends or retracts, it drives the second connecting rod 47 to rotate relative to the frame 5, further driving the first connecting rod 46 to rotate and translate, and further driving the translation member 44 to translate along the translation guide 43. The aforementioned drive device 41, translation member 44, first connecting rod 46, and second connecting rod 47 all move in the XY axis plane, without increasing the height of the buffer transport device.

[0052] In this embodiment, the telescopic drive device 41 is an electric push rod.

[0053] An electric linear actuator is an electrically driven device that converts the rotary motion of an electric motor into the linear reciprocating motion of a linear actuator. It mainly consists of a motor, a linear actuator, and a control device, and is a new type of linear execution mechanism. Electric linear actuators can be used in various simple or complex processes to achieve remote control, centralized control, or automatic control. Electric linear actuators are characterized by their novel and refined design, small size, high precision, and perfect synchronization. They also offer advantages such as compact structure, convenient installation, reliable use, simple maintenance, and energy saving.

[0054] In this embodiment, both sides of the material input end of the conveying mechanism 2 are provided with inlet guides 21. The inlet guides 21 are provided with guide slopes 211. The guide slopes 211 of the two inlet guides 21 are opposite to each other. Along the positive X-axis direction, the distance between the guide slopes 211 of the two inlet guides 21 gradually increases.

[0055] The aforementioned entrance guide 21 is a guide plate. The space between the two entrance guides 21 is the channel for the flower basket to enter the buffer space 3. When the flower basket passes through the channel, the channel is initially wide, and the flower basket can easily enter the channel. As the channel narrows, the channel guides and corrects the entering flower basket, so that the flower basket can eventually move accurately onto the conveying mechanism 2.

[0056] In this embodiment, the buffer handling device further includes a housing 6, which is connected to the frame 5 above and to the side of the buffer space 3. The housing 6 has a material transfer port 61 facing the positive X-axis direction. The conveying mechanism 2 is located at the bottom of the housing 6 and passes through the material transfer port 61. The limiting mechanism is located inside the housing 6. The driving device 41 is located inside the housing 6. When the stop member 42 is in the stop position, the stop member 42 is located at the material transfer port 61.

[0057] By installing the housing 6, the flower basket, conveyor mechanism 2, and drive device 41 in the buffer space 3 can be protected from dust and dust. For example, in the event of an accidental collision, the housing 6 can provide a certain degree of cushioning.

[0058] In this embodiment, the aforementioned mobile mechanism 1 is a robot mobile chassis that can move autonomously.

[0059] A robot mobile chassis is the part of a robot used for movement and steering, responsible for the robot's motion and task execution. It typically consists of structural components, wheels, and drive circuitry. Its main function is to handle the robot's movement and steering, ensuring that the robot can complete tasks according to a preset path or through autonomous navigation. The mobile mechanism in this invention utilizes an existing autonomous robot mobile chassis.

[0060] In this embodiment, the conveying mechanism 2 is a belt conveyor mechanism.

[0061] A belt conveyor is a mechanical device used for the continuous transport of materials. It transports various materials through the continuous movement of a conveyor belt. The conveyor belt is wrapped between a drive drum and a driven drum. The rotation of the drive drum causes the conveyor belt to move, thereby transporting the material from the starting point to the ending point.

[0062] In this embodiment, the buffer handling device further includes a limiting mechanism, which is used to restrict the material in the buffer space 3 from moving and dumping in other directions. The limiting mechanism includes a limiting baffle 71, which restricts the material in the buffer space 3 from moving and dumping in the positive Y-axis direction and the negative Y-axis direction.

[0063] The aforementioned limiting mechanism is used to restrict the material in the aforementioned buffer space 3 from translating and tipping in directions other than the positive X-axis direction. Generally, the conveying mechanism 2 is equipped with the aforementioned limiting mechanism. During the handling process, the flower basket generally moves forward or turns to the side, which causes the flower basket to easily tip over in the direction of movement and to the side due to inertia. Based on the aforementioned movable stop mechanism, a limiting baffle 71 is further provided. Since the limiting baffle 71 does not need to release the flower basket, it can be set as a fixed baffle, and its height is relatively high. The limiting baffle 71 is in contact with at least the center of gravity of the material in the aforementioned buffer space 3 or a position above the center of gravity.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
