[0026] Reference Figure 1 As an embodiment of this utility model, a screw fastening device includes a machine base 1, a screw fastening mechanism 2, and a dispensing mechanism 3. The screw fastening mechanism 2 is mounted on the machine base 1 and includes a screw chamber 21, a fastening track 22, a feeding track 23, and a fastening head 24. The fastening track 22 is arranged along a first direction of the machine base 1 and is located above the feeding track 23. The feeding track 23 is arranged along a second direction of the machine base 1, which is perpendicular to the first direction. A first material tray 25 is slidably connected to the feeding track 23. The fastening head 24 is slidably connected to the fastening track 22 and can pick up screws from the screw chamber 21 and install them onto the material in the first material tray 25. The dispensing mechanism 3 includes a dispensing head 31, which is mounted on and slidably connected to the fastening track 22. The dispensing head 31 and the fastening head 24 slide alternately.

[0027] The screw fastening device includes a screw fastening mechanism 2 and a dispensing mechanism 3. A screw fastening head 24 is slidably connected to a screw fastening track 22. The screw fastening head 24 can pick up screws from the screw magazine 21 and install them onto the material in the first material tray 25. The first material tray 25 can slide on the feeding track 23 for position adjustment, facilitating screw installation. When dispensing is required after screw installation, the dispensing head slides directly on the screw fastening track 22 to directly above the material and performs the dispensing operation. By integrating the screw fastening mechanism 2 and the dispensing structure into one screw fastening device, the assembly efficiency of parts is greatly improved. Simultaneously, the screw fastening head 24 and the dispensing head 31 share a single screw fastening track 22, saving equipment costs while meeting functional requirements.

[0028] Specifically, the screw compartment 21 is located below the fastening track 22. The fastening head 24 includes a fastening electric screwdriver 241, a rotary drive mechanism, and a lifting mechanism 242. The lifting mechanism 242 drives the fastening electric screwdriver 241 to rise and fall, while the rotary drive mechanism drives the screwdriver to rotate. The fastening head 24 can slide along the fastening track 22 to directly above the screw compartment 21. The lifting mechanism 242 drives the fastening electric screwdriver 241 to descend until it contacts the screw in the screw compartment 21. The screw compartment 21 has a feeding mechanism that can feed screws, ensuring they are neatly arranged. The fastening electric screwdriver 241 is magnetically attached, allowing it to directly attract screws. A CCD camera is located on one side of the fastening electric screwdriver 241, which can scan and photograph the position of the screw, allowing the fastening electric screwdriver 241 to be rotated and adjusted accordingly, ensuring it is precisely inserted into the screw's insertion hole. After the screwdriver 241 picks up the screw, it slides along the screwdriver track 22 to directly above the material. Then, driven by the lifting mechanism 242, the screwdriver 241 moves down again and is placed in the designated position. Finally, the rotation drive mechanism drives the screwdriver to rotate, so as to tighten and lock the screw.

[0029] In this embodiment, the locking electric screwdriver 241 is provided with a torque adjustment mechanism. The torque adjustment mechanism adjusts the torque of the electric screwdriver rotation, which can control the magnitude of the torque and prevent the screw from stripping.

[0030] The feeding track 23 is provided with a first driving device on one side. The first driving device drives the first material tray 25 to slide along the feeding track 23, so as to facilitate the first material tray 25 to be moved directly below the locking track 22, thereby facilitating the locking electric screwdriver 241 on the locking track 22 to perform locking operations.

[0031] Furthermore, the dispensing mechanism 3 also includes a dispensing track 32, on which a second material tray 33 is provided. The dispensing track 32 is arranged side by side with and parallel to the feeding track 23. The locking track 22 is mounted above the feeding track 23 and the dispensing track 32.

[0032] Specifically, the dispensing track 32 and the feeding track 23 are arranged side by side and parallel to the feeding track 23, and they work independently without interfering with each other. The fastening track 22 is erected above the feeding track 23 and the dispensing track 32, allowing the fastening and dispensing operations to be carried out independently without interference. When the workpiece requires both fastening and dispensing, the dispensing head 31 and the fastening head 24 can slide alternately on the fastening track 22, facilitating continuous operation of the fastening and dispensing processes. The dispensing head 31 includes a glue tank, a dispensing head, and a lifting unit. The lifting unit drives the dispensing head to move up and down to the designated position on the material for dispensing. The dispensing head is connected to the glue tank, and the glue in the tank can be drawn out by a suction pump or other power components and dispensed at the designated position through the dispensing head. The glue storage tank is connected to the dispensing head via a glue delivery pipe. The glue delivery pipe is equipped with a flow control valve, which can be adjusted according to actual needs to precisely control the glue delivery flow rate.

[0033] The dispensing mechanism 3 also includes an air pressure supply unit, which includes an air source, an air pressure regulating valve, and an air storage tank. The air storage tank is connected to the glue storage tank. The air source provides the initial air pressure, and the air pressure regulating valve is used to precisely adjust the air pressure input to the air storage tank. The air storage tank can stably store a certain amount of compressed air to provide a continuous and stable air pressure to the glue storage tank, reducing the impact of air pressure fluctuations on glue extrusion.

[0034] The dispensing mechanism 3 also includes a negative pressure back suction unit, which is located on one side of the dispensing head. The negative pressure back suction unit draws the residual glue in the dispensing head back into the glue storage tank. When dispensing is finished, the negative pressure back suction unit is activated, generating negative pressure to draw the residual glue in the dispensing head back into the glue storage tank or a special recycling device, effectively preventing stringing and dripping caused by glue residue.

[0035] The adhesive storage tank is equipped with a heating component and a stirring component. For high-viscosity adhesives, the heating component in the storage tank can moderately heat the adhesive, reducing its viscosity and making it easier to flow and extrude. Simultaneously, the stirring component agitates the adhesive during the dispensing process, ensuring uniformity, preventing sedimentation or stratification, and further improving the dispensing effect.

[0036] In this embodiment, the screw fastening device includes a screw fastening mechanism 2 and a dispensing mechanism 3. A screw fastening head 24 is slidably connected to a screw fastening track 22. The screw fastening head 24 can pick up screws from the screw magazine 21 and install them onto the material in the first material tray 25. The first material tray 25 can slide on the feeding track 23 for position adjustment, facilitating screw installation. When dispensing is required after screw installation, the dispensing head slides directly on the screw fastening track 22 to directly above the material and performs the dispensing operation. By integrating the screw fastening mechanism 2 and the dispensing structure into one screw fastening device, the assembly efficiency of parts is greatly improved. Simultaneously, the screw fastening head 24 and the dispensing head 31 share a single screw fastening track 22, saving equipment costs while meeting functional requirements.
