[0020] To solve the problem of how to effectively prevent slippage, such as Figure 1-4 As shown, the following preferred technical solutions are provided:
[0021] A robotic arm with anti-slip components includes a robotic arm body 1. A rectangular box 2 is fixedly mounted at the output end of the robotic arm body 1. Four evenly distributed clamping plates 7 are provided at the bottom of the rectangular box 2. Anti-slip pads 14 are attached to the inner side of the clamping plates 7. Four evenly distributed racks 8 are provided on the inner bottom surface of the rectangular box 2. Corresponding gears 9 are provided at the upper end of the racks 8. Corresponding clamping plates 7 are connected to the lower end of the racks 8. A motor 13 is provided at the corner of the inner bottom surface of the rectangular box 2. The motor 13 drives the four gears 9 to rotate synchronously, which is used to ultimately drive the four clamping plates 7 to move synchronously towards or away from each other.
[0022] Specifically, when the robotic arm 1 needs to clamp the product, the motor 13 first starts and drives the four gears 9 to rotate synchronously. Through engagement with the corresponding racks 8, the four racks 8 move synchronously outwards, causing the four clamping plates 7 to move synchronously outwards to a certain position. Then, the motor 13 stops. Next, the output end of the robotic arm 1 moves the four clamping plates 7 to the outside of the product. Then, the motor 13 starts and reverses, driving the four gears 9 to rotate synchronously inwards. Through engagement with the racks 8, the four racks 8 move synchronously towards each other, causing the four clamping plates 7 to move synchronously towards each other. The anti-slip pads 14 on the inner side of the clamping plates 7 clamp and fix the outer side of the product. Finally, the output end of the robotic arm 1 moves the product. The purpose of this design is to clamp and fix the outer side of the product by the synchronously moving anti-slip pads 14 attached to the inner side of the four clamping plates 7, effectively transferring the product through multi-point clamping and improved anti-slip performance, preventing it from falling.
[0023] Furthermore, such as Figure 2-4 As shown, the following preferred technical solutions are provided:
[0024] The rectangular box 2 has four evenly distributed rectangular holes 4 inside. Fixed rods 5 are fixed at both ends of the inner sidewall of the rectangular holes 4. A connecting plate 6 is fixed at the middle of the upper end of the clamping plate 7. The upper end of the connecting plate 6 is slidably connected to the outside of the fixed rods 5. The upper outer side of the connecting plate 6 is slidably connected to the inside of the rectangular holes 4. The upper end of the connecting plate 6 is fixedly connected to the bottom edge of the corresponding rack 8. The purpose of this design is to ensure that the rack 8 moves and the clamping plate 7 moves synchronously through the connecting plate 6.
[0025] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0026] Gear 9 is connected to rack 8. A rotating rod 10 is fixedly installed in the middle of gear 9. Bevel gears 11 are symmetrically installed at both ends of rotating rod 10. A support plate 12 is provided on one side of the end of rotating rod 10. The bottom end of support plate 12 is fixed on the bottom surface of rectangular box 2. The outer side of rotating rod 10 is rotatably connected to the inside of support plate 12 through bearings. Two adjacent bevel gears 11 mesh with each other. The purpose of this design is to ensure that gear 9 can rotate stably. By meshing with rack 8, it drives rack 8 to move. In addition, by meshing with two adjacent bevel gears 11, the four rotating rods 10 can transmit power to each other.
[0027] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0028] The motor 13 is fixedly mounted on the bottom surface of the rectangular box 2 via a mounting plate. The output end of the motor 13 is fixedly connected to the end of the corresponding rotating rod 10. The purpose of this design is that the motor 13 drives one of the rotating rods 10 to rotate, and through transmission, drives the other three rotating rods 10 to rotate synchronously, thereby driving the four gears 9 to rotate synchronously. By meshing with the rack 8, the four racks 8 are driven to move synchronously, thereby driving the four clamping plates 7 to move synchronously.
[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:
[0030] The rectangular box 2 has side openings 3 on all four sides, through which the corresponding racks 8 pass. The purpose of this design is to ensure that the racks 8 can move without interfering with the position adjustment of the clamps 7.
[0031] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:
[0032] The connecting plates 6 do not interfere with each other; this design aims to ensure structural rationality.
[0033] In summary: When the robotic arm 1 needs to clamp a product, the motor 13 first starts and drives the four gears 9 to rotate synchronously. Through engagement with the corresponding racks 8, the four racks 8 move synchronously outwards, causing the four clamping plates 7 to move synchronously outwards to a certain position. Then, the motor 13 stops. Next, the output end of the robotic arm 1 moves the four clamping plates 7 to the outside of the product. Then, the motor 13 starts and reverses, driving the four gears 9 to rotate synchronously inwards. Through engagement with the racks 8, the four racks 8 move synchronously towards each other, causing the four clamping plates 7 to move synchronously towards each other. The anti-slip pads 14 on the inner side of the clamping plates 7 clamp and fix the outer side of the product. Finally, the output end of the robotic arm 1 moves the product. The purpose of this design is to clamp and fix the outer side of the product by the synchronously moving anti-slip pads 14 attached to the inner side of the four clamping plates 7, effectively transferring the product through multi-point clamping and improved anti-slip performance, preventing it from falling.
