Description

Technical Field

[0001] This utility model relates to the field of silicon wafer flower baskets, and in particular to a device for preventing silicon wafer flower baskets from tipping over. Background Technology

[0002] In existing technologies, silicon wafers need to be transferred between different processes during solar cell production. Currently, the industry typically uses automated wafer loading machines with wafer baskets for loading and a circulating system to transport the wafers. These wafer baskets have a certain height and can bear a certain weight after loading the wafers. When transported between processes via the circulating system, the wafer baskets are prone to tipping or wobbling, which can easily cause damage, wafers falling and breaking, or even injuring nearby workers, posing significant production and safety hazards. Current methods often reduce the conveyor speed to decrease the probability of wafer basket tipping; however, this not only fails to completely solve the tipping problem but also reduces work efficiency and production capacity.

However, this not only fails to completely solve the problem of silicon wafer basket tipping, but also reduces work efficiency and production capacity.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0008] As a further improvement to the above technical solution: a first groove is provided on the base; the linkage includes a first rack, a first gear meshing with the first rack, a second rack meshing with the first gear, a second gear meshing with the second rack, and a connecting rod disposed on the second gear; a connecting groove is provided on the pressing member; the first gear is disposed in the connecting groove; the first gear rotates in the first groove; a second groove is provided on the base; the second rack slides in the second groove; the second gear rotates in the second groove; the first gear simultaneously meshes with both the first rack and the second rack; a third groove is provided on the base; the connecting rod rotates in the third groove.

[0009] As a further improvement to the above technical solution: a fourth groove is provided at the bottom of the first groove; the fourth groove provides slack for the downward movement of the first rack.

[0010] As a further improvement to the above technical solution: a guide rod is provided inside the second groove; the guide rod passes through the second rack; a reset member is provided inside the second groove; one end of the reset member is fixed to the second groove, and the other end of the reset member is fixed to the second rack; when the pressing member presses down, it drives the first gear to rotate, thereby driving the second rack to slide.

[0011] As a further improvement to the above technical solution: a fifth groove is provided on the connecting rod; the limiting member slides along the fifth groove; a fixing member is threadedly connected to the connecting rod; the position of the limiting member can be adjusted according to different flower baskets; the fixing member restricts the position of the limiting member.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. The design utilizes a pressing mechanism that drives the first gear to rotate when pressed down, causing the second rack to slide and stretch the reset component. This, combined with a connecting rod, forces the limiting component to rotate to a preset angle, creating a rigid three-point constraint that simultaneously locks the bottom and sidewalls of the basket, resisting transport vibrations or sudden stop impacts. The reset component (e.g., a spring) automatically rebounds after the pressing component is released, resetting the linkage mechanism to its initial state. The limiting component then simultaneously disengages from the basket, enabling rapid loading and unloading cycles, eliminating the need for manual unlocking, and adapting to high-speed automated production lines. The fifth slot on the connecting rod allows the limiting component to slide and adjust its position, and after locking with a fixing component, it adapts to baskets of different sizes. The chamfered corner of the limiting block precisely matches the base slot, guiding the basket to quickly align and insert. Combined with the guide rod constraining the movement trajectory of the second rack, it ensures consistent rotation angles of the limiting component. The self-locking characteristic of the gear and rack transmission ensures that external force cannot reverse the movement in the locked state, preventing accidental unlocking. The limiting component is made of high-hardness material, resistant to high-frequency impact wear. The base slot and the limiting component form a semi-enclosed space, preventing dust from entering the linkage mechanism; the guide rod and the reset component are coated with a corrosion-resistant coating, which is suitable for the high humidity environment of the cleaning process and reduces the failure rate.

[0018] This application provides a silicon wafer basket anti-tipping device, which solves the problem that the existing technology usually reduces the conveying speed of the conveying device to reduce the probability of silicon wafer basket tipping. However, this not only fails to completely solve the problem of silicon wafer basket tipping, but also reduces work efficiency and production capacity.

[0019] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] A silicon wafer flower basket anti-tipping device includes a base 1, a limiting member 2 for limiting the flower basket, a pressing member 3 that abuts against the bottom of the flower basket, a linkage member 4 that links the limiting member 2 and the pressing member 3, and a limiting block 5 for easy installation; the limiting blocks 5 are arranged in an array and the limiting blocks 5 restrict the flower basket between the limiting blocks 5; the pressing member 3 moves up and down on the base 1; the linkage member 4 is disposed in the base 1; the limiting member 2 is disposed at the actuating end of the linkage member 4; when the flower basket presses down on the pressing member 3, it drives the limiting member 2 to rotate at an angle until the pressing member 3 is completely embedded in the base 1 and the limiting member 2 restricts the position of the flower basket.

[0022] The base 1 has a slot 6; the slot 6 is the same size as the flower basket.

[0023] The limiting block 5 has a chamfer 51; the chamfer 51 facilitates the quick installation of the flower basket into the slot 6.

[0024] The base 1 has a first groove 11; the linkage 4 includes a first rack 41, a first gear 42 meshing with the first rack 41, a second rack 43 meshing with the first gear 42, a second gear 45 meshing with the second rack 43, and a connecting rod 46 disposed on the second gear 45; the pressing member 3 has a connecting groove 31; the first gear 42 is disposed in the connecting groove 31; the first gear 42 rotates in the first groove 11; the base 1 has a second groove 12; the second rack 43 slides in the second groove 12; the second gear 45 rotates in the second groove 12; the first gear 42 simultaneously meshes with the first rack 41 and the second rack 43; the base 1 has a third groove 13; the connecting rod 46 rotates in the third groove 13.

[0025] A fourth groove 14 is provided at the bottom of the first groove 11; the fourth groove 14 provides slack for the downward movement of the first rack 41.

[0026] A guide rod 15 is provided inside the second groove 12; the guide rod 15 passes through the second rack 43; a reset member 16 is provided inside the second groove 12; one end of the reset member 16 is fixed to the second groove 12, and the other end of the reset member 16 is fixed to the second rack 43; when the pressing member 3 is pressed down, it drives the first gear 42 to rotate, thereby driving the second rack 43 to slide. At this time, the reset member 16 is stretched and the second gear 45 rotates, thereby driving the connecting rod 46 to rotate.

[0027] The connecting rod 46 has a fifth groove 461; the limiting member 2 slides along the fifth groove 461; the connecting rod 46 is threaded with a fixing member 462; the limiting member 2 can be adjusted according to different flower baskets; the fixing member 462 restricts the position of the limiting member 2.

[0028] When the pressing part 3 is pressed down, it drives the first gear 42 to rotate, causing the second rack 43 to slide and stretch the reset part 16. Through the connecting rod 46, the limiting part 2 is forced to rotate to a preset angle, forming a rigid three-point constraint, which locks the bottom and side wall of the flower basket at the same time to resist transportation vibration or sudden stop impact. After the pressing part 3 is released, the reset part 16 (such as a spring) automatically rebounds, driving the linkage mechanism to reset to the initial state. The limiting part 2 is simultaneously released from the flower basket, realizing a quick loading and unloading cycle, avoiding manual unlocking steps, and adapting to the cycle time of high-speed automated production lines.

The chamfer 51 of the limiting block 5 is precisely matched with the slot 6 of the base 1, guiding the flower basket to be quickly centered and inserted. Combined with the guide rod 15, it constrains the movement trajectory of the second rack 43 and ensures the consistency of the rotation angle of the limiting part 2. The self-locking characteristic of the gear and rack transmission ensures that external force cannot drive in the reverse direction when locked, preventing accidental unlocking.

The base 1 and the slot 6 form a semi-enclosed space with the limiting component 2, preventing dust from entering the linkage mechanism; the guide rod 15 and the reset component 16 are coated with a corrosion-resistant coating, which is suitable for the high humidity environment of the cleaning process and reduces the failure rate.

[0029] The pressing component 3 drives the first gear 42 to rotate when pressed down, which in turn drives the second rack 43 to slide and stretch the reset component 16. The connecting rod 46 forces the limiting component 2 to rotate to a preset angle, forming a rigid three-point constraint that simultaneously locks the bottom and side wall of the flower basket, resisting transportation vibration or sudden stop impact. The reset component 16 (such as a spring) automatically rebounds after the pressing component 3 is released, driving the linkage mechanism to reset to the initial state. The limiting component 2 simultaneously disengages from the flower basket, realizing a rapid loading and unloading cycle, avoiding manual unlocking steps, and adapting to the pace of high-speed automated production lines. The fifth groove 461 on the connecting rod 46 allows the limiting component 2 to slide and adjust its position. After being locked by the fixing component 462, it adapts to flower baskets of different sizes. The chamfer 51 of the limiting block 5 precisely matches the slot 6 of the base 1, guiding the flower basket to be quickly centered and inserted. Combined with the guide rod 15, it constrains the movement trajectory of the second rack 43, ensuring the consistency of the rotation angle of the limiting component 2. The self-locking characteristic of the gear and rack transmission ensures that external force cannot drive in the reverse direction when locked, preventing accidental unlocking. The limiting component 2 is made of high-hardness material, which can withstand high-frequency impact wear. The base 1 and the slot 6 form a semi-enclosed space with the limiting component 2, preventing dust from entering the linkage mechanism; the guide rod 15 and the reset component 16 are coated with a corrosion-resistant coating, which is suitable for the high humidity environment of the cleaning process and reduces the failure rate.
