Figures 1 to 3 The described embodiments are exemplary and are intended to explain the embodiments of the present invention, but should not be understood as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0025] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0026] In one embodiment of the present invention, Figures 1 to 3 As shown, a screw locking machine for locking screws of a tablet computer is provided, comprising a frame 10, a conveying device 20, a first detection sensor 30, a second detection sensor 40, a screw locking device 50 and a positioning device 60; the positioning device 60 and the screw locking device 50 are both arranged on the frame 10, and the positioning device 60 is located directly below the screw locking device 50; the conveying stroke of the conveying device 20 is located between the screw locking devices 50, and is used to convey the tablet computer; the first detection sensor 30 is used to detect the number of tablet computers conveyed; the second detection sensor 40 is arranged on the frame 10 or on the conveying device 20, and the second detection sensor 40 is located next to the positioning device 60, and is used to detect whether the tablet computer has reached the screw locking position and send a signal to the positioning device 60 and the conveying device 20, and the positioning device 60 fixes the tablet computer so that the tablet computer is located at the bottom of the screw locking device 50.

[0027] During operation, the tablet is placed on the mold for secure transportation to protect the tablet's housing. The mold is placed on the conveyor 20 and transported to the screw-locking position. When the tablet passes the first detection sensor 30, the first detection sensor 30 senses the tablet, collects relevant data, and transmits a signal to the screw-locking device 50 to reset and prepare for operation. When the conveyor 20 conveys the tablet past the second detection sensor 40, the second detection sensor 40 senses the tablet, and the conveyor 20 stops conveying. The positioning device 60 activates to fix the mold on the tablet, and then the screw-locking device 50 starts to screw the tablet. Once completed, the positioning mechanism releases the clamp, and the conveyor 20 resumes conveyance. This achieves automated positioning and screw-locking, eliminating the need for manual operation and requiring only a set program. This achieves high precision and high efficiency.

[0028] In this example, the positioning device 60 includes a first limiting mechanism 61 and a second limiting mechanism 62, arranged sequentially along the tablet computer's conveying direction. The first limiting mechanism 61 is used to secure one side of the tablet computer, while the second limiting mechanism 62 is used to secure the other side of the tablet computer. The first limiting mechanism 61 and the second limiting mechanism 62 are arranged opposite each other, and the second limiting mechanism 62 can move toward the first limiting mechanism 61 to secure the tablet computer. Specifically, the first limiting mechanism 61 and the second limiting mechanism 62 can be housed below the conveying surface of the conveyor device 20, or they can be driven to extend above the conveying surface to secure the tablet computer on the screw position.

[0029] In this example, the first limiting mechanism 61 includes a first mounting base 611, a first driving element 612, and a first limiting plate 613. The first mounting base 611 is mounted on the frame 10, the first driving element 612 is mounted on the first mounting base 611, and the first limiting plate 613 is mounted on the movable end of the first driving element 612. The first limiting plate 613 is driven to extend beyond the conveying surface of the conveyor 20 to limit the movement of the tablet computer. Specifically, the first mounting base 611 can be screwed to the frame 10, and the first driving element 612 drives the first limiting plate 613 to move up and down.

[0030] In this example, the second limiting mechanism 62 includes a second mounting seat 621, a second driving element 622, a third driving element 623, and a second limiting plate 624. The second mounting seat 621 is mounted on the frame 10, and the second driving element 622 is mounted on the second mounting seat 621. The third driving element 623 is mounted on the movable end of the second driving element 622 and is driven to move vertically. The second limiting plate 624 is mounted on the movable end of the third driving element 623 and is driven to move horizontally in a direction toward or away from the first limiting mechanism 61. Specifically, the second mounting seat 621 can be screwed to the frame 10, and the second mounting seat 621 is arranged opposite the first mounting seat 611. The second driving element 622 drives the third driving element 623 to move up and down. The second limiting plate 624 is an L-shaped plate.

[0031] The process of positioning and securing the tablet computer is as follows: the second detection sensor 40 senses the tablet computer, the conveyor 20 stops conveying, and the second drive element 622 drives the third drive element 623 upward until one end of the second limit plate 624 extends beyond the conveying surface of the conveyor 20. The first drive element 612 drives the first limit plate 613 upward until one end of the first limit plate 613 extends beyond the conveying surface of the conveyor 20. At this point, the tablet computer is positioned between the first limit plate 613 and the second limit plate 624. The third drive element 623 then drives the second limit plate 624 toward the first limit plate 613. During this movement, the second limit plate 624 contacts the tablet computer and drags it toward the first limit plate 613 until it is positioned between the two limit plates, thereby securing the tablet computer. Since the first limit plate 613 is fixed, the second limit plate 624 adjusts the tablet computer to the screw locking position based on the first limit plate 613, positioning the screw locking device 50 directly above the tablet computer for precise screw locking.

[0032] In this example, the first driving element 612 , the second driving element 622 , and the third driving element 623 are all driving cylinders.

[0033] In this example, the conveyor device 20 includes a first belt conveyor mechanism 21 and a second belt conveyor mechanism 22. The input end of the second belt conveyor mechanism 22 is located at the output end of the first belt conveyor mechanism 21. The first detection sensor 30 is disposed at the output end of the first belt conveyor mechanism 21. The second belt conveyor mechanism 22 is disposed on the frame 10. Specifically, the second belt conveyor mechanism 22 is composed of two sets of parallel and spaced belt conveyor assemblies. The positioning device 60 is located between the two belt conveyor assemblies to ensure that the two limit plates can extend and retract from the conveying surface of the conveyor device 20.

[0034] In this example, the screw locking device 50 includes a lifting mechanism 51, a driving mechanism 52, and a screw locking mechanism 53. The lifting mechanism 51 is mounted on the frame 10, and the screw locking mechanism 53 is located at the lifting end of the lifting mechanism 51. The driving mechanism 52 is located at the top of the screw locking mechanism 53 and is used to drive the screw locking mechanism 53 to rotate. Specifically, the lifting mechanism 51 is a lifting cylinder, and the driving mechanism 52 includes a transmission module for the drive motor. The transmission module connects the drive motor and the screw locking mechanism 53, thereby rotating the screw locking mechanism 53 to lock the screw.

[0035] In this example, the screw locking mechanism 53 includes a connecting seat 531, a connecting rod assembly 532, a buffer assembly 533, and a screw adsorption head 534. The connecting seat 531 is connected to the lifting end of the lifting mechanism 51. The connecting rod assembly 532 is rotatably arranged on the connecting seat 531 and connected to the driving mechanism 52. The connecting rod assembly 532 is connected to the screw adsorption head 534, and the screw adsorption head 534 is used to adsorb screws. The buffer assembly 533 connects the connecting seat 531 and the screw adsorption head 534. Specifically, the screw adsorption head 534 is magnetic and can adsorb screws. The screw adsorption head 534 is connected to a negative pressure mechanism, which can further adsorb the screw by generating negative pressure, while avoiding the problem of the screw being easily swung left and right by magnetic adsorption alone, and the screw adsorption effect is more stable. The buffer assembly 533 cooperates with the connecting rod assembly 532 to prevent the screw locking process and the screw locking mechanism 53 from causing damage to the tablet computer.

[0036] In this example, the connecting rod assembly 532 includes a first connecting rod 5321 and a second connecting rod 5322. One end of the first connecting rod 5321 is connected to the driving mechanism 52, and the other end is rotatably connected to the second connecting rod 5322. One end of the second connecting rod 5322 is connected to the screw adsorption head 534. Specifically, because the second connecting rod 5322 is rotatably connected to the first connecting rod 5321 and the second connecting rod 5322 is arranged vertically, during buffering, the force applied to the second connecting rod 5322 causes the first connecting rod 5321 to rotate, thereby preventing a hard collision.

[0037] In this example, the buffer assembly 533 includes a top plate 5331, a bottom plate 5332, a guide post 5333, and a spring 5334. The top plate 5331 is connected to the connecting base 531. One end of the guide post 5333 passes through the top plate 5331 and the other end is connected to the bottom plate 5332. The bottom plate 5332 is connected to the screw adsorption head 534. The spring 5334 is sleeved on the outside of the guide post 5333 and is located between the top plate 5331 and the bottom plate 5332. Specifically, the guide post 5333 can slide relative to the top plate 5331, and the bottom plate 5332 is forced to compress the spring 5334 to produce an elastic buffering effect. The guide post 5333 can ensure the stability of the structure.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
