Technical Field

[0001] This invention relates to the field of automated assembly equipment technology, specifically to an automated miniature screw fastening device. Background Technology

[0002] Common electronic devices such as mobile phones, tablets, and laptops are assembled from multiple components, most of which are secured with screws. Currently, most electronic devices use automated screw fastening equipment to fasten these screws. However, existing automated screw fastening equipment can generally only assemble electronic devices of a single size and cannot meet the production needs of a variety of electronic products.

[0003] For example, an existing automatic screw fastening device, with publication number CN107322281A, "includes a worktable, on which a product placement fixture for fixing products and a screw feeder are provided; an XZ-axis robot arm is mounted on the worktable; an electric screwdriver and a camera are fixedly connected to the XZ-axis robot arm; a suction nozzle is connected to the bottom end of the screwdriver bit; a drive assembly is mounted on the XZ-axis robot arm; the automatic screw fastening device also includes a control terminal." Although it eliminates the need for manual screw fastening, it can only assemble electronic devices of a single size and cannot meet the production needs of various electronic products. Therefore, a new type of automated miniature screw fastening device is needed. Summary of the Invention

[0076] Working principle:

[0077] Before operation, the automated miniature screw fastening device loosens the sliding locking mechanism 1707 to allow the moving drive assembly 1704 to slide along the third linear guide assembly 1705, thereby adjusting the distance between the fixed drive assembly 1703 and the moving drive assembly 1704 to adapt to product assemblies 1716 of different sizes and improve the versatility of the production line 17.

[0078] During operation, product assembly 1716 is placed at the first station of production line 17 and paused under the obstruction of the first station blocking module 1708. The barcode scanner 1502 scans the bottom of product assembly 1716 to identify the model number. Then, product assembly 1716 continues to the second station, where it pauses under the obstruction of the second station blocking module 1708, facilitating the vacuum screw fastening machine 1010 to pick up screws of different models. Simultaneously, the lifting module 1709 adsorbs product assembly 1716, and the front and rear clamping modules... Group 1711 and left and right clamping modules 1710 press against product assembly 1716. Screw guide rod 1714 assists vacuum screw fastening machine 1010 to fasten screw body 1716F onto product assembly 1716. Finally, product assembly 1716 moves forward to the third station. Blocking module 1708, front and rear clamping modules 1711 and left and right clamping modules 1710 together fix product assembly 1716. Pressure holding module 14 presses and holds the adhesive strip 1716C adhered to product assembly 1716. During screw fastening, the vacuum screw fastening machine 1010 picks up the screw body 1716F from the screw feeder body 1101 and moves it to the lower CCD module 12 for identification and positioning. At the same time, the upper CCD positioning module 13 locates and identifies the screw hole position on the product assembly 1716 and transmits the information to the control mechanism of the vacuum screw fastening machine 1010. Finally, the product assemblies 1716 labeled as track one and track two on the production line 17 are merged into a single track for the next process. Figure 24 This is a flowchart illustrating the operation of this device.

Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
