Description

Technical Field

[0001] This utility model relates to the field of electronic product fastening technology, and in particular to a screw machine applicable to a variety of electronic products. Background Technology

[0002] Screw fastening machines are widely used automated equipment in the electronics manufacturing industry. Their main function is to automatically feed and fasten screws. In the production of electronic products such as laptops, tablets, and monitors, the assembly of the casing often relies on screw connections. Screw fastening machines can significantly improve the efficiency and consistency of casing fastening, thereby ensuring the stability of product quality.

[0003] However, existing screw-making machines have certain limitations. Currently, most screw-making machines on the market are customized for specific product categories, and their positioning structures are usually only suitable for specific specifications or models of products. This design approach leads to the following problems in practical applications:

[0004] First, when screw fastening machines are used for other product categories, insufficient adaptability of the positioning structure can easily lead to positioning instability, which in turn affects the accuracy and reliability of subsequent fastening operations. This instability may result in screws not being properly fastened or uneven fastening force, ultimately affecting the assembly quality of the product.

[0005] Secondly, customized screw-making machines have limitations in their applicability. When products are updated or production lines are changed, the original screw-making machines may no longer be able to adapt to the new production needs, resulting in idle equipment. This not only reduces equipment utilization but also wastes production resources and increases the company's production costs.

[0006] In summary, existing screw machines have significant shortcomings in terms of the versatility and adaptability of their positioning structures, making it difficult to meet the diverse and rapidly iterating production needs in electronic product manufacturing. Utility Model Content

The conveying unit has a fastening area. The machine is characterized by further including a turntable 2 that can be conveyed on the conveying unit.

[0044] The positioning unit includes a pressing drive device 3. The output end of the pressing drive device 3 is connected to a pressing plate 4. The pressing plate 4 has several locking clearance holes 5. The pressing drive device 3 acts on the pressing plate 4 so that the pressing plate 4 can press the turntable 2 into the locking area.

[0045] In this embodiment, the conveying unit is used to convey the turntable 2 and the electronic products to be fastened; the positioning unit is used to position the turntable 2; the feeding unit is used to supply screws one by one so that the fastening unit can grab them; and the fastening unit is used to perform the fastening operation on the electronic products.

[0046] In application, the turntable 2 is considered a positioning structure that can be separated from the screw-making machine. Maintaining the consistency of the turntable 2's external dimensions, only the shape of the internal grooves needs to be changed to perform initial positioning of various electronic products, such as laptops, tablets, and monitors. The turntable 2 containing the electronic products is then placed on the conveyor unit, which transports it to the locking area. The pressing drive 3 is then activated, lowering the pressure plate 4 until it presses the electronic product firmly into the locking area. At this point, the screws can be tightened onto the electronic product through the locking clearance hole 5. It is important to note that the opening position of the locking clearance hole 5 should match the position on the electronic product to be screwed.
