It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0017] like Figure 3 As shown, this application primarily addresses the purpose of using this production line to assemble the same type of nut on different products. Compared to existing manual assembly methods, assembly efficiency is improved, the assembly quality rate is also increased, and omissions or incorrect assembly are avoided. Furthermore, it is applicable to different products, reducing assembly costs. The specific composition of this production line is as follows: like Figure 1-12 As shown, a universal high-speed nut press-fitting production line includes, The press-fit turntable 12 is used as the center, and the turntables are arranged sequentially around it, with the rotation direction being from installing nuts 14 to installing semi-finished products and then installing nuts 14 onto semi-finished products. Nut loading station 7 is used to place nuts on the pressing turntable 12 when it rotates to the station position. Specifically, the nut loading station includes a spider robot, a flexible vibrating plate and a vision camera. The flexible vibrating plate is used to disperse the nuts piled together on the vibrating plate for easy picking. The spider robot is used to take the nuts out of the vibrating plate and place them on the pressing base. The vision camera determines the picking and placing position. The semi-finished product loading and handling mechanism 2 is used to invert the semi-finished product onto the nut on the carrier 16 on the press turntable 12 when the press turntable 12 rotates to the work station position, so that the nut is installed on the semi-finished product; specifically, it is a four-axis robot. Nut pressing mechanism 3 is used to press the nut onto the semi-finished product when the pressing turntable 12 rotates to the position of the work station; Inspection turntable 13 is located near the pressing turntable 12; Product flipping and handling station 5 is used to transport the product formed by pressing the nut and semi-finished product 15 to the inspection turntable 13 via the carrier 16 on the pressing turntable 12; Nut height detection station 9 is used to detect the height of nuts on the product as the detection turntable 13 rotates; QR code reading station 10 is used to read the content of QR codes and determine the QR code level via the barcode reader on it; The nut height detection station 9 and the QR code reading station 10 determine whether the product is good or not.

[0018] A semi-finished product conveyor line 1 is arranged near the pressing turntable 12, and the semi-finished product conveyor line 1 is located near the semi-finished product loading and handling mechanism 2. It is used to transport products to the vicinity of the semi-finished product loading and handling mechanism 2 via the semi-finished product conveyor line 1, and the semi-finished product is transferred to the pressing turntable 12 via the semi-finished product loading and handling mechanism 2. Specifically, the semi-finished product loading and handling mechanism 2 consists of a four-axis robot and a picking clamp 21 installed on it. When the semi-finished product is transported to the vicinity of the loading and handling mechanism 2 via the semi-finished product conveyor line 1, the movement of the robotic arm on the four-axis robot causes the picking clamp 21 on it to approach the semi-finished product located on the semi-finished product conveyor line 1, and then pick up the semi-finished product and place it on the pressing turntable 12 to match the nut on the pressing turntable 12.

[0019] The nut height detection station 9 includes a first linear bearing and a camera assembly, and the assembly is an XY-oriented structure.

[0023] Next to the pressing turntable 12, there is also a nut residue detection station 6, which is located between the product flipping and handling station 5 and the nut loading station 7. It is used to detect whether there are any residual nuts on the pressing turntable 12 after the assembled product is transported to the detection turntable 13, so as to avoid the situation of overlapping nuts. The press-fitting seat nut missing detection station 8 is located between the nut loading station 7 and the semi-finished product loading and handling mechanism 2. It is used to detect whether nuts are installed on the press-fitting turntable 12 to prevent missing nuts.

[0024] Near the inspection turntable 3, there is also a finished product unloading station 11, which is used to unload the product after it has been inspected by both the nut height inspection station 9 and the QR code reading station 10.

[0025] Furthermore, the finished product unloading station 11 is a combination of a second linear bearing and a cylinder suction cup, and the combination is an XY structure. The second linear bearing is arranged in the horizontal direction, the fixed end of the cylinder is fixed to the sliding part on the second linear bearing, the free end of the cylinder is arranged in the vertical direction, and the suction cup is installed on the free end of the cylinder and is arranged downward in the vertical direction.

They are used to place good products into the good product outlet and defective products into the defective product chute for separation through the cooperation of the second linear bearing and the cylinder suction cup assembly.

[0026] The following example, using a semi-finished product from this production line matched with a nut to form a finished product, illustrates its working principle: Step 1. This involves two aspects. First, the nut loading station loads nuts onto the carrier 16 on the pressing turntable. Second, as the pressing turntable with nuts rotates to the vicinity of the semi-finished product loading and handling mechanism, the semi-finished product conveyor line and the semi-finished product loading and handling mechanism work together (specifically: the semi-finished product is placed onto the feeding conveyor line 1 by a robotic arm, and the semi-finished product is transported to the loading position by the conveyor line; after the semi-finished product arrives at the loading position, the four-axis robot uses vacuum suction to transport the semi-finished product to the carrier of the pressing turntable 12), and the semi-finished product 15 is fastened to the nut on the pressing turntable to achieve contact between the nut and the semi-finished product 15. Step 2. After the material is loaded, the turntable rotates the semi-finished product to the pressing station 3, and the nut is pressed into the semi-finished product 15 by the cylinder; Step 3. After the product assembly is completed, it goes to the flipping and handling station 5. This station uses a rotary cylinder and a gripper cylinder to flip the product 180 degrees, that is, flip it from the original upside-down state to the normal state, and then transport it from the pressing turntable 12 to the inspection turntable 13 for inspection. Step 4. After the product is transported to the inspection turntable 13, it will be moved to the height inspection station 9, where a 3D line scan camera will be used to inspect the height of the nuts after they are pressed in. Step 5. After the height detection is completed, proceed to the QR code reading station 10 and the unloading station 11, which are the same station. The QR code content is read by the code reader and the QR code level is determined. The product is determined to be a good product by detecting the nut height and the QR code level. Finally, the servo unloading mechanism 11 transports the product to the good product slide or the defective product slide according to the judgment result.

[0027] In addition, after the product passes from the pressing turntable 12 to the inspection turntable 13, as the pressing turntable 12 rotates, the nut residue inspection station 6 is used to check whether there are any left on the pressing turntable 12, so as to avoid the situation of overlapping nuts. After the carrier is inspected, it enters the nut loading station 7, which is an integrated system of spider robot, flexible vibratory plate and vision camera, to place the nut 14 on the pressing carrier 12. After nut 14 is placed, it will enter the next press-fitting seat nut missing detection station 8 to check whether the nut is placed on the carrier. After the detection is completed, it will enter the semi-finished product loading station 2 to wait for the four-axis robot to transport the semi-finished product for the press-fitting operation of the next product.

[0028] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
