DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Embodiment: A device for automatically locking screws of a paper feeder cover of a printer, such as Figure 1 and Figure 4 As shown, it includes a support block 3, a first guide rod 301, an emergency button 4, a slider 5, a first electric slide rail 501, a placement mechanism and a locking mechanism. The first guide rod 301 is fixedly connected to the opposite side of the two support blocks 3. The first guide rod 301 is slidably connected to the placement mechanism for placing the workpiece. The side wall of the support block 3 is installed with a first electric slide rail 501. The slider 5 on the first electric slide rail 501 passes through the support block 3 and limits the placement mechanism. An emergency button 4 is installed on one of the support blocks 3. The emergency button 4 is electrically connected to the first electric slide rail 501. A locking mechanism for locking screws is commonly provided on the top of the two support blocks 3. Here, when an error in the device program causes the device to fail to work normally, the emergency button 4 can be pressed. The emergency button 4 sends an instruction to the first electric slide rail 501. The first electric slide rail 501 responds to the instruction. The first electric slide rail 501 drives the slider 5 to slide outward. The slider 5 releases the restriction on the placement mechanism. The placement mechanism falls downward under the influence of gravity, so that the screwdriver cannot lock the screw, causing the device to stop working in an emergency.

[0023] like Figure 3 and Figure 5 As shown, the placement mechanism includes a mounting plate 9, a support plate 901, a connecting rod 902, a second guide rod 903 and a spring 904. The first guide rod 301 is slidably connected to the support plate 901, and the middle of the support plate 901 is fixedly connected to the mounting plate 9. The circumferential side walls of the mounting plate 9 are provided with fixed blocks. A group of fixed blocks on adjacent side walls of the mounting plate 9 are fixedly connected to the mounting plate 9. The inside of the mounting plate 9 is fixedly connected to the second guide rod 903. The second guide rod 903 is slidably connected to the connecting rod 902. The fixed blocks on another group of adjacent side walls of the mounting plate 9 are fixedly connected to the connecting rod 902. Next, a spring 904 is wound around the second guide rod 903, and the two ends of the spring 904 are respectively connected to the connecting rod 902 and the mounting plate 9. Here, the fixing block is pulled outward to make the connecting rod 902 slide outward along the second guide rod 903. At this time, the spring 904 is compressed, and then the printer feeder and the printer feeder cover are placed on the mounting plate 9. After that, the fixing block is released, and the spring 904 drives the connecting rod 902 to slide inward through its own resilience. The connecting rod 902 squeezes the printer feeder and the printer feeder cover, thereby fixing the printer feeder and the printer feeder cover.

[0024] like Figure 2 and Figure 3 As shown, the locking mechanism includes a second electric slide rail 7, a third electric slide rail 8 and a rotating device 11. The second electric slide rail 7 is commonly provided on the top of the two support blocks 3, and the third electric slide rail 8 is provided on the slide rail of the second electric slide rail 7. The rotating device 11 is slidably installed on the third electric slide rail 8. An electric push rod 6 is provided between the support block 3 and the second electric slide rail 7. Here, the second electric slide rail 7 drives the third electric slide rail 8 to move left and right, and the third electric slide rail 8 drives the rotating device 11 to move back and forth. At the same time, the rotating device 11 works in conjunction with components such as sensors to achieve precise positioning of the screws within the moving range of the second electric slide rail 7 and the third electric slide rail 8. The telescopic rod of the electric push rod 6 slides downward, and the telescopic rod of the electric push rod 6 drives the second electric slide rail 7 to slide downward, so that the screwdriver contacts the screw to screw the printer feeder cover.

[0025] like Figure 1 As shown, a shell 1 is provided between the two support blocks 3, and the second electric slide rail 7 passes through the shell 1. A group of transparent door panels 2 are rotatably connected to one side of the shell 1. Here, the transparent door panels 2 can provide an inspection window for workers, making it convenient for workers to observe the operating status of the device. The shell 1 and the transparent door panels 2 are combined to form a box with an internal accommodating space. The design of the shell 1 and the transparent door panels 2 can separate the working space of the device to prevent endangering the lives of workers when the device fails.

[0026] like Figure 2As shown, a rubber pad 10 is fixedly connected between the two support blocks 2. The rubber pad 10 is arranged under the mounting plate 9. Here, the design of the rubber pad 10 can provide a buffer for the support plate 901 when the support plate 901 falls downward, thereby minimizing damage to device parts and the printer feeder cover.

[0027] This device is needed when the printer feeder cover needs to be installed. First, flip the transparent door panel 2 outward 180 degrees to open the device, then pull the fixing block outward to make the connecting rod 902 slide outward along the second guide rod 903. At this time, the spring 904 is compressed, and then the printer feeder and the printer feeder cover are placed on the mounting plate 9. After that, the fixing block is released, and the spring 904 drives the connecting rod 902 to slide inward through its own resilience, thereby fixing the printer feeder and the printer feeder cover. Then place the screws at the specific position of the printer feeder cover, flip the transparent door panel 2 inward 180 degrees, close the device, and then start the second electric slide 7 and the third electric slide 8. The second electric slide 7 drives the third electric slide 8 to move left and right, and the third electric slide 8 drives the rotating device 11 to move back and forth. At the same time, the rotating device 11 works in conjunction with sensors and other components to achieve precise positioning of the screws within the moving range of the second electric slide 7 and the third electric slide 8. After positioning, the rotating device 11 drives the screwdriver installed on the rotating device 11 to rotate, and finally slides downward through the telescopic rod of the electric push rod 6. The telescopic rod of the electric push rod 6 drives the second electric slide 7 to slide downward, so that the screwdriver contacts the screw and the printer feeder cover screw is locked. When a program error occurs in the device that causes the device to fail to work properly, the emergency button 4 can be pressed. The emergency button 4 sends an instruction to the first electric slide 501. The first electric slide 501 responds to the instruction. The first electric slide 501 drives the slider 5 to slide outward. The slider 5 releases the restriction on the support plate 901. The support plate 901 falls downward under the influence of gravity, making it impossible for the screwdriver to contact the printer feeder cover screws, causing the device to stop working in an emergency to prevent the device from erroneous operation due to an erroneous program.

[0028] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
