[0046] 1. By setting up an automatic feeding device, the automatic feeding device can realize the automatic feeding function, improve the efficiency of material transportation, save manual labor, and have a high level of automation;

[0047] 2. By equipping the assembly mechanism with an adsorption device, the adsorption device transports materials through an electromagnet, and the studs will be adsorbed on the adsorption mold to improve the stability of transportation. At the same time, the adsorption mold can be replaced according to the model of the bolt, which can improve its practicality and ensure that the studs will not shake during the assembly process, and ensure that the studs and nuts can be installed vertically.

[0048] 3. By setting up an automatic identification device, the automatic identification device can automatically identify whether the bolts are qualified. Such a setting can reduce the subsequent manual classification work of the staff, save labor, realize intelligent assembly, and further improve the level of automation;

[0049] 4.

[0050] 5. The bottom plate of the support groove is connected by rotating it on the connecting seat by using a forward and reverse motor. In the assembly process, the controller controls the forward and reverse motor to be in a balanced position, and the bottom plate is also in a balanced position. When the automatic identification device identifies that the bolt is qualified and transmits the signal to the controller, the controller feeds back an electrical signal to the forward and reverse motor to control the forward and reverse motor to rotate the bottom plate, so as to close the unqualified channel and open the qualified channel. When the automatic identification device identifies that the bolt is unqualified and transmits the signal to the controller, the controller feeds back an electrical signal to the forward and reverse motor to control the forward and reverse motor to rotate the bottom plate, so as to close the qualified channel and open the unqualified channel. In this way, the intelligent automatic identification, classification and recycling function is realized, which further reduces the work tasks of the staff, saves labor productivity and improves production efficiency.

[0051] The specific working principle of the present invention is as follows: first, the staff will pour the produced studs and nuts into the storage boxes of the automatic feeding mechanism on both sides of the assembly mechanism respectively, and then control the first driving cylinder to be driven by the controller. The first driving cylinder rotates the feeding rack around the support seat through telescopic movement, and feeds the bolts / nuts in the storage box to the transport guide rail (when the nut reaches the support groove and the bolt reaches the limit block). When the nut and the bolt reach the specified position, the transverse transport mechanism will control the transverse cylinder to drive the mounting block to move transversely, and the longitudinal control device on the mounting block will move with the mounting block until it is directly above the stud next to the limit block. Then the longitudinal cylinder drives the electromagnet to move downward to suck up the stud. After the stud is sucked up, it is transported again by the transverse cylinder. To the specified position, the rotating device and the longitudinal control device start to operate, controlling the stud to screw downward into the nut; during the screwing process, when the reaction force received by the pressure sensor from the stud is greater than the originally set maximum rated pressure, and its displacement reaches the originally set rated displacement, it means that the stud and the nut are not compatible, and the controller receives a signal that the product is unqualified; when the reaction force received by the pressure sensor from the stud is less than or equal to the originally set maximum rated pressure and can reach the rated displacement, it means that the stud and the nut are compatible, and the controller receives a signal that the product is qualified; the controller controls the forward and reverse motor to drive the bottom plate to perform forward and reverse operations according to the received electrical signals, so as to achieve the effect of automatically recovering qualified and unqualified products; and it runs repeatedly in this way.

[0053] In a specific embodiment of the present invention, a method for assembling a bolt includes the following steps:

[0054] S1 Material preparation: First, the staff pours the produced studs and nuts into the storage boxes of the automatic feeding mechanism on both sides of the assembly mechanism to prepare the materials;

[0055] S2 Loading: The loading device on the automatic loading mechanism drives the loading rack through the first driving cylinder to transport the studs and nuts to their respective transport rails;

[0056] S3 transport: The studs in the transport track can be adsorbed on the bottom of the driving bracket by the electromagnetic sticker on the adsorption device, and transported to the top of the support slot by the transverse driving mechanism, while the nuts in the other transport track are transported to the support slot by the nut longitudinal pushing part and the nut transverse pushing part respectively;

[0057] S4 assembly: At this point, the controller controls the drive motor and the longitudinal cylinder to screw the stud down into the nut;

[0058] S5 identification: During the screwing process, when the reaction force from the stud received by the pressure sensor is greater than the originally set maximum rated pressure, and its displacement reaches the originally set rated displacement, it means that the stud and the nut are not compatible, and the controller receives a signal that the product is unqualified; when the reaction force from the stud received by the pressure sensor is less than or equal to the originally set maximum rated pressure and can reach the rated displacement, it means that the stud and the nut are compatible, and the controller receives a signal that the product is qualified;

[0059] S6 Classification Recycling: The controller controls the forward and reverse motor to drive the bottom plate to perform forward and reverse operations according to the received electrical signals, so as to achieve the effect of automatically recycling qualified and unqualified products.

[0060] Compared with the prior art, the beneficial effects brought about by the present assembly method are: through such an assembly method, the degree of automation and intelligence of assembly is improved, and the assembly efficiency is improved, labor is saved, and production costs are saved.
