[0002] At present, during the production process of silicon wafers, they generally need to be placed in flower baskets for transportation. During loading and unloading, the silicon wafers on the flower baskets are generally transported to processing equipment through a conveying mechanism for processing, and the processed silicon wafers are then placed back into the flower baskets.

[0003] When the existing loading and unloading devices are in use, generally, a manipulator is used to move the flower basket loaded with silicon wafers to a belt conveyor for loading. However, after loading is completed, workers need to manually carry the flower basket to the unloading equipment, and then the manipulator moves the flower basket to the unloading equipment for unloading. The loading and unloading are troublesome, and during loading and unloading, the flower basket is prone to tipping due to external forces, resulting in poor use effects. For this reason, we propose an automatic loading and unloading device for flower baskets. Summary of the Utility Model

Detailed Embodiment

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Referring to Figures 1 - 5 , a flower basket automatic loading and unloading device includes a base 1. Two support bottom plates 15 are provided on one side of the base 1. The bottom of the base 1 is connected to the support bottom plates 15 through legs 16. Two guide rails 14 are symmetrically installed on the top of each support bottom plate 15. Each guide rail 14 is connected with a linear driving module 17. The tops of adjacent two linear driving modules 17 are connected through a U-shaped frame 18. A control cabinet 19 is installed on one side of the U-shaped frame 18. A controller is provided inside the control cabinet 19. The controller is one of a control main board or a PLC logic controller, and the controller is connected to the linear driving module 17 through a wire. During actual use, the linear driving module 17 can be controlled by the controller to move horizontally along the guide rail 14, so as to adjust the horizontal position of the U-shaped frame 18.

[0028] Such as Figure 1As shown, several pairs of support seats 3 are equidistantly installed on the top of the base 1. A conveying roller 2 is rotatably connected between each pair of support seats 3. A flower basket is provided on the top of the conveying roller 2, and the conveying rollers 2 are connected by a driving mechanism. The specific structure of the driving mechanism is as follows: The driving mechanism includes a sprocket 21 installed at one end of each conveying roller 2. Adjacent sprockets 21 are connected by a chain, and a second driving motor 23 is installed at the end of the conveying roller 2 located at one end. The second driving motor 23 is fixed on the support seat 3. The second driving motor 23 is connected to the controller through a wire. By driving the second driving motor 23, the conveying roller 2 can be driven to rotate, and thus the flower basket placed on the conveying roller 2 can be automatically conveyed.

[0029] As Figure 1 and Figure 2 As shown, a strip-shaped connecting plate 7 is provided inside each U-shaped frame 18. Two forklifts 8 are installed on the top of each strip-shaped connecting plate 7. One end of each forklift 8 extends above the base 1 and is located in the gap between adjacent conveying rollers 2. During actual use, the U-shaped frame 18 can be driven to move horizontally by the linear driving module 17, so that one end of the forklift 8 extends to the bottom of the conveying roller 2.

[0030] As Figure 1 and Figure 4 As shown, fixing blocks 13 are installed on both sides inside each U-shaped frame 18. A lead screw 11 is rotatably connected between each fixing block 13 and the top of the U-shaped frame 18. Adjacent lead screws 11 penetrate through the strip-shaped connecting plate 7 and are in threaded cooperation with the strip-shaped connecting plate 7. A gearbox 10 is installed on the top of each U-shaped frame 18. A first driving motor 9 is installed on the top of the gearbox 10. The output shaft of the first driving motor 9 is connected to adjacent lead screws 11 through the gearbox 10. The first driving motor 9 is connected to the controller through a wire. During actual use, the controller can control the first driving motor 9 to work. Under the action of the gearbox 10, the two lead screws 11 can be driven to rotate synchronously, and thus the height of the strip-shaped connecting plate 7 and the forklift 8 can be adjusted as needed.

[0031] It should be noted that an infrared sensor 22 is installed on the top of each forklift 8. The infrared sensor 22 is connected to the controller through a wire. When the flower basket moves above the forklift 8 under the action of the conveying roller 2, the infrared sensors 22 on the two adjacent forklifts 8 can detect the position of the flower basket and transmit the signal to the controller. When the flower basket moves to the preset position, the controller turns off the second driving motor 23 and simultaneously controls the first driving motor 9 to work. The first driving motor 9 can drive the forklift 8 to move under the action of the lead screw 11 and lift the flower basket located above the forklift 8.

[0032] It should be noted that as Figure 1As shown in the figure, belt conveyors 24 are provided on one side of the U-shaped frame 18, and the bottom of the belt conveyor 24 is fixed on the support bottom plate 15 through support columns. The width of the belt conveyor 24 is smaller than the width of the U-shaped frame 18. During actual use, when the forklift 8 jacks up the flower basket, the controller controls the linear drive module 17 to control the horizontal movement of the U-shaped frame 18, so that the flower basket on the forklift 8 can be moved to one end of the belt conveyor 24.

[0033] It should be noted that as Figure 4 or Figure 5 shown in the figure, a pair of limit plates 20 are vertically installed at the top of each forklift 8, and the adjacent surfaces of each pair of limit plates 20 are in contact with the bottom edge of the flower basket. During actual use, when the belt conveyor 24 removes the silicon wafers from the flower basket or the belt conveyor 24 transports the silicon wafers to the flower basket, under the action of the limit plates 20, the flower basket will not move or tip over.

[0034] As Figure 1 shown in the figure, several pairs of vertical plates 12 are installed on the top of the base 1. A cross plate 5 is vertically installed on the top of each pair of vertical plates 12, and one side of each cross plate 5 extends above the conveying roller 2. Several connecting shafts 6 are rotatably connected to the top of each cross plate 5, and a limit wheel 4 is installed at the bottom of each connecting shaft 6. One side of the limit wheel 4 extends outside the cross plate 5, and the side surface of the limit wheel 4 is in contact with the side surface of the flower basket. During actual conveying, the limit wheel 4 can limit the flower basket on the conveying roller 2 to prevent the flower basket from tipping over during conveying, and the limit wheel 4 can also limit the flower basket on the conveying roller 2 to prevent the position of the flower basket from shifting.

[0035] It should be noted that there is a spacing between two adjacent pairs of vertical plates 12. One end of the forklift 8 is located within this spacing, and there is also a spacing between the forklift 8 and the vertical plate 12, so that the forklift 8 will not collide with the vertical plate 12 when moving.

[0036] Specifically, when the utility model is in use, the staff places the flower basket containing silicon wafers on the conveying roller 2. The controller controls the second driving motor 23 to work, and the conveying roller 2 rotates to convey the flower basket. When the flower basket moves to the preset position at the top of the two forklifts 8, the infrared sensor 22 transmits a signal to the controller. The controller turns off the second driving motor 23 and at the same time controls the first driving motor 9 to work. The first driving motor 9 drives the lead screw 11 to rotate, causing the forklift 8 to move upward and lift the flower basket. Then the controller controls the linear driving module 17 to work. The linear driving module 17 drives the U-shaped frame 18 to move horizontally, so that the forklift 8 and the flower basket are moved out of the top of the base 1. Then the first driving motor 9 reverses, and the forklift 8 moves downward, so that the flower basket moves to the preset height. Then the linear driving module 17 moves the flower basket to one end of one of the belt conveyors 24. The silicon wafers on the flower basket come into contact with the belt conveyor 24. Under the action of the belt conveyor 24, the silicon wafers on the flower basket can be moved out and conveyed to the processing equipment for processing. While the belt conveyor 24 is conveying the silicon wafers, the first driving motor 9 keeps reversing, and the stacked silicon wafers on the flower basket are sequentially moved out through the belt conveyor 24. When the silicon wafers on the flower basket are completely moved out, the controller controls the linear driving module 17 to move towards the direction of the base 1, and the flower basket is separated from the belt conveyor 24. Then it controls the first driving motor 9 to rotate forward, and the forklift 8 and the flower basket move upward. When the forklift 8 and the flower basket move above the cross plate 5, under the action of the linear driving module 17, the forklift 8 and the flower basket move above the conveying roller 2. Then it controls the first driving motor 9 to reverse, so that the flower basket moves downward and contacts the top of the conveying roller 2. Then the controller controls the second driving motor 23 to work, and the conveying roller 2 conveys the empty flower basket to a preset position above another pair of forklifts 8. The infrared sensor 22 on the forklift 8 transmits the model to the controller, and the controller then controls the first driving motor 9 and the linear driving module 17 to move the empty flower basket to one end of another belt conveyor 24. This belt conveyor 24 can sequentially move the processed silicon wafers into the flower basket to complete the loading and unloading.

[0037] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
